BULLFIX 3125922 Extra Heavy Duty Plasterboard Fixings
Installation Instructions
STEP 1
- We recommend using a cable finder to detect any existing cables behind the plasterboard
- Mark out the hole centre with a pencil or marking tool
- Using a 20mm diameter spade bit, drill a hole
IMPORTANT: Only apply a gentle pressure whilst drilling to avoid damaging the rear of the plasterboard.
Bullfix Extra fixings are designed to be used with standard (12.5mm to 16mm) thickness plasterboard attached to stud partition walls. To operate properly they require a minimum cavity depth of 20mm (with shallower cavities the fin tails will not be able to open properly).
STEP 2
- Insert the collar and gently tap with a mallet
STEP 3
- Push the closed fixing gently through the collar with the fin tails aligned vertically
- Pinch the projected fin tails together
STEP 4
- Tap the rear of the fixing until the two halves of the fixing hole align to accept a screw
IMPORTANT: If the plasterboard is more than 12.5mm thick the fixing may slide into the collar, this is normal. You may also need to tap a little harder the thicker the plasterboard.
STEP 5
- Attach the object to the wall using the screws provided or any standard 5mm (No 10) screws
- To maximise performance, the screw should be long enough to reach the back of the fixing. If not, a longer screw should be used.
- To achieve the very maximum load capacity in plasterboard which is more than 12.5mm thick, we recommend using washers to fill the gap between the front faces of the fixing and the plasterboard.
IMPORTANT: We do not recommend using screws that travel more than 36mm past the front surface unless you know the cavity is deeper.

Maximum load strengths are dependent on plasterboard thickness, humidity and brand. Please refer to the datasheet on www.bullfix.co.uk for more information.
WE DO NOT RECOMMEND USING BULLFIX FOR TV MOUNTS WITH A CANTILEVER OR EXTENDABLE ARM AS WE CANNOT GUARANTEE THE RELIABILITY. IDEAL FOR USE WITH A FIXED OR TILTING TV BRACKETS.

- Maximum recommended loads apply to plasterboard (British Gypsum Gyproc Wallboard) in a dry condition. Please note that variations in board mounting, moisture content, plasterboard brand or physical condition of board can adversely effect load bearing performance. Continuous and repetitive loading / unloading on the fixing will weaken plasterboard.
- All recommended loads assume a minimum distance from the edge of the board of 50mm
- When using multiple fixings, to maintain the best performance for the fixing we would recommend you keep a minimum center distance of 90mm between fixings.
- For all maximum recommended loads required safety factors are considered.
- Fixing Material – Glass Filled Nylon.
TV Mounting Brackets:
We do not recommend using Bullfix plasterboard fixings with TV mounting
extendable arms.
Any bracket that extends the center of gravity of any loading further than
150mm from the wall will risk exceeding the capability of the plasterboard
fixing and in fact the plasterboard itself. We only recommend Bullfix
plasterboard fixings for use with flat or tilting TV wall brackets.
Radiator or Shelf Brackets:
We only recommend mounting items on plasterboard with Bullfix fixings using an
appropriate bracket. The bracket should adhere to the specification shown
below.
”Y” must be at least 1.5 times bigger than “X”
