SECURE GUIDE

MASONRY BLOCK CONSTRUCTION

WARNING! Masonry blockwork should be properly filled and reinforced if brackets are to be mounted directly to blockwork with masonry anchors.
Where the blockwork is not solidly filled but structurally sound, long bolts should be passed through the blockwork using suitable steel plates under bolt heads.
Special consideration should be given to brick type and construction of wall, to ensure satisfactory fixing e.g. welding detail if fixed to steel.

preparation

WARNING! If you need to remove an old door prior to installing a B&D door ensure to:

• Roll the door up and place a secure tie around the middle
• Place door support on flat ground
• Fit door support snugly under door before loosening the brackets or locating U bolts.
• Slowly undo bolts to release the spring tension and the door from the brackets.
• Slowly lift the door from the brackets keeping it balanced as it is lowered to the ground.

before installation

requirements

mounting – The door is designed to be mounted behind the opening.
obstructions – Ensure that the surface where the door will be fitted is flush and smooth, and the area behind the opening is free from any protrusions.
structural suitability – Ensure the opening is strong enough to support the door. If unsure, consult a builder.
level and plumb – The door must be installed in an absolutely level position, if opening is not level and square, appearance and/ or sideroom requirements will be affected. The floor should be level or recessed across the opening to avoid gaps.

DO NOT CUT THE PACKAGING THAT HOLDS THE DOOR IN A ROLL
At a later stage during the installation you will be told just when to cut the packaging. Remove brackets, guides and bag of small parts from each end of the door roll.

measurements

opening width – As the standard door overlaps each side by 50mm or more, the door should be 100mm wider than the opening. A wider door can be fitted as long as additional side room and fixing is available.
(Fig 1.4.1a) Wind-Locked doors require additional overlap dependent on the substrate, consult the B&D High Wind Certification Drawings for more detail.

opening height – The door opening height (or drive through clearance) indicates the distance between the ground and rubber seal at the bottom of the door, with door fully open. Max drive through heights for each door height are listed in Fig 1.4.1b.
headroom – A minimum headroom is required for all doors. Refer to Fig 1.4.2 – 1.4.5 for measurements. If the door is installed lower into the opening than shown in Fig 1.4.2, additional loss of door opening height will result.
backroom – A minimum of 460mm of backroom is required for R2L doors up to 2400mm. For other doors, refer to Fig 1.4.2 – 1.4.5 for measurements.

Take note of drive through clearance heights in fig 1.4.2b as the bottom rail will hang into the opening on some doors, therefore reducing the opening.

a) Use above diagrams Fig 2.1.1 and 2.1.2 for head and sideroom clearances.

b) Mark three hole positions using slots of the bracket B .
c) Drill holes, then attach bracket using six 10mm (3/8”) bolt size masonry anchors; (dyna bolts or similar).

WARNING! The structure substrate must conform to the DTCM requirements. Refer to bac.nt.gov.au for the DTCM Manual or High Wind drawings on the B&D Website.

install second bracket

a) Using a water level mark the position for the second bracket (Fig 2.2.1)

b) Re-check levels then drill and fix as with first bracket.

CAUTION : The brackets must be perfectly level for the door to operate.

place door on brackets

TWO PERSON LIFT : this product requires a two person lift to raise onto the brackets. Use proper techniques and equipment to lift the door from the trailer and up onto brackets.

CAUTION: DO NOT CUT THE PLASTIC WRAP OR PACKAGING YET

a) Check the axle length and cut if side room is limited. Before cutting, make sure the floating axle is free and centred (Fig 2.3.1). Centre will be found by rotating the axle a quarter turn in either direction then releasing . With centre found, make a clear mark on the axle against the hub for later reference.

b) With the door the correct way round (the curtain rolls down the rear of the opening) carefully lift door onto the brackets using block and tackles attached to the door axles, or other suitable lifting equipment – to avoid curtain damage.
c) Loosely fit “U” bolt J and/or saddle K , or double saddle and position the door so that it overlaps the opening evenly both sides so that the axle is positioned on the bracket arm slots as far forward as possible (Fig 2.3.2) Fitting the saddles eliminates the door falling from the brackets.

d) Centre the door with the opening, while ensuring the floating axle is also centred with the door.
Do this by lining up previous marks with the hub, then lift both the axle and the door together until it is centred with the opening. Rotate both the door and the axle so that the bottom rail is level with the arm of the bracket.
e) Now tighten the “U” bolts saddle K , or double saddle (door size dependent), using washers under nuts L , to a torque of 40 newton metres or 30 ft.lb.

install guides

positioning guides

WARNING! Do not grease the guides. Grease will damage the Nylofelt® running strips and make doors heavier to operate.

CAUTION : Restricted headroom installation is not recommended for automated doors unless the door is installed lower into the opening. NOTE: This will reduce the drive through height.

R2F has a maximum width of 5100mm.
*R2L Only, above 2400mm only available in WA

WARNING! All High Wind installations must adhere to fixing types and centres as referenced in the DTCM Drawings and B&D High Wind Drawings.

If securing to uneven brickwork, packers may be required behind clips, to prevent them twisting out of square; also ensure that clips are positioned on secure bricks.

a) Check that curtain overlaps equally on both sides.
b) Check that guides C are the correct length, that is, starts level with the brackets (or as per table above at position G). (Fig 2.4.1) If guides need to be shortened cut from bottom of guide.

c) For Series 2 Doors:
(i) Now position one guide over the edge of the door curtain. Mark and drill the top fixed guide clip and secure using correct fixing and washers as per table in Section 1.2, allowing 3-4mm clearance between the door and the inside of the guide.
(ii) Ensuring guide is plumb, using spirit level, then drill and fix remaining clips and head stop.
For Series 2 Windlock Doors:
(i) If there is limited sideroom available the guide may need to have the side cut out to accommodate. See Fig 2.4.2 for recommended and restricted sideroom with a clearance of 2-5mm to the bottom rail roller.

(ii) Now position one guide over the edge of the door curtain. Mark and drill at top guide hole and secure guide using fixing types as per High Wind Certification Drawings, taking note of the specific spacing requirements.
(iii) Ensuring guide is plumb, drill and fix remaining holes in guide as per spacing details listed.
d) With the top of the 2nd guide level with the first, repeat (c) for the specific door type.

NOTE : Welding of guides to steelwork is usually not recommended

tension the springs

WARNING! Once the packaging containing the door roll is cut, the door will have a strong tendency to rise and revolve. If uncontrolled, the rapidly unrolling door could cause damage or injury.

tensioning and adjustments

a) Ensure that the bottom rail is at the 9 o’clock position as shown in Fig 2.5.1.

b) Ensure both “U” bolts are tightened, then –
1. Rotate the door approximately 2 complete turns in a forward direction to apply tension. Do not let go as the springs are now tensioned. See arrow in Fig 2.5.1.
2. Hold the door firmly, NOW cut the plastic wrap along the bottom rail (taking care not to damage door surface).
c) Pull the curtain down slowly into the guides below the head stop in Fig 2.5.2.

d) Fit bottom rail stops E using self locking nuts provided. Allow the door to rise and rest against head stops Fig 2.5.3.

e) Test the door operation by moving it up and down. The curtain must feed in smoothly without bumping.
f) Reposition the guides as necessary to allow smooth and even operation with clearances shown below throughout. See images in Fig 2.5.4 for each specific guide / wind region, adjust lead in as required Step 2.5.2.

creating proper guide lead-in

The shape of lead-in is critical for successful door operation and trouble free performance. The shape of lead-in needs to be formed by the installer, refer to (fig 2.5.5).

a) With multigrips, bend top 5mm of lead-in approximately 45° to prevent Nylofelt® catching on lead-in.
b) Bend lead-in from door stop to top of lead-in (along press cut), to finish 15mm from its original position.
c) Check top of guide lead-in to ensure that the door does not make contact when rotated. Damage to Nylofelt® could result.

WARNING! For all doors that are fitted with openers. To reduce the risk of damage to persons or property, be sure to cut off any excess thread of the screw that protrudes the weight bottle and file any burs.

locking

Appendix

after installation care

cleaning

COLORBOND® and coloured steel FINISH DOORS: Your B&D Roll-A-Door® door has been pre-painted with a high durability polyester paint system especially designed and tested for the harsh Australian conditions. However, all exposed surfaces require some attention to guard against the premature onset of corrosion and any other harmful atmospheric effects. In our atmosphere there are harmful deposits that gather on the door surface and if not removed regularly, will seriously affect the appearance and life of the door.
Washing of the door with clean water and a cloth every 14 days is recommended – particular care should be taken to clean areas of the door not normally washed by rain, including the top of the door roll inside the garage. NOTE: In locations where there is likely to be salt in the air or industrial fallout is severe, more frequent washing is advisable and additional protection of the surface maybe required.
Touch-up paint, if required, is available from your B&D dealer

lock
Your lock does not require special maintenance, however, if the keyway becomes stiff, the application of powdered graphite is recommended – do not grease or oil the lock.
The faceplate should be washed with soapy water and rinsed well. Strong solvents, such as acetone, should not be used – these will damage the surface. WARNING! Do not disassemble the lock mechanism.
When opening the door, always make sure the key is with drawn from the lock – if this is not done, the lock mechanism could be damaged and the key bent or broken.
We suggest you record your full Key letter and Number on the front of this manual and if replacement keys are required they can be obtained from your nearest B&D office, simply by quoting this number. If the keys have been lost and the number not recorded, it can be found stamped into the locking arm at the back of the mechanism.

NYLOFELT®
On no account should you use grease or oil in the door guides or on the Nylofelt® running strips – the grease or oil will clog the Nylofelt® and spoil the operation of the door. An occasional wipe with a cloth dampened with mineral turps or methylated spirits, down the inside of each guide, is very beneficial in removing any trace of grease or dirt.
After the guides have been cleaned, a silicon spray may be used in the guides.
NOTE : WD40 or similar oil based sprays are not silicon and should not be used.

Care should be taken not to damage the Nylofelt®, however, if Nylofelt® is cut or damaged, a lighted match should be used to quickly seal the ends of the nylon braiding, so as to stop any further deterioration.

regular maintenance required
B&D recommends that you check the operation of your Roll-A-Door® at least every six months (more regularly in extreme environments or frequent use). The effort required to manually open and to manually close the door should be about the same (if door has an automatic opener, put into manual mode before testing door). If the door is difficult to operate in either direction (up or down) then check:

1. that the Nylofelt® running strips on each side of the door have not slipped from the edge and are jamming the door;
2. that the door is running correctly in the guides and the guides are straight and perpendicular; and
3. that the inside surfaces of the guides are clean and free of obstructions. (see paragraph on care of Nylofelt®)

If you have checked these (and corrected where necessary) and the door is still difficult to operate, , then your door will need a service to adjust the spring tension and possibly other operational parts of the door. This service should only be carried out by an experienced door technician, using the correct tools.
If you have an automatic opener fitted to your door, it is particularly important that you ensure the optimum operation of the door, otherwise you may reduce the effective life of the opener.
To keep your door running well, it is recommended that your door be serviced, by an experienced door technician, every 12 months (more regularly in extreme environments or frequent use), or earlier if required.

spring tension
It is natural for springs to lose tension over time. When spring tension is adjusted or when your door is first installed it is usual to apply a little more tension than is required for balanced operation, to allow for the normal “settling in” of the springs.
warranty
