THINGS TO KNOW ABOUT CABLE BULLET HANDRAIL

1. IT’S DESIGNED TO BE CUT DOWN FOR CUSTOM LENGTHS
   Use a miter saw and a non-ferrous metal cutting blade for any custom cut length. Before cutting, wrap the handrail in painter’s tape to minimize chipping. After cutting, file away any burrs inside the handrail. Before removing the painter’s tape, spray your ends with touch-up spray to cover any blemishes.

2. SECTIONS ARE JOINED WITH INTERNAL, CONCEALED SPLINES
   Piece together longer handrail sections with fixed or adjustable splines. Splines are tapered and will tighten up as they are inserted into the handrail.

Piece together longer, level sections. Does not need to be supported over a post.| | ADJ. STRAIGHT
Use where a level straight run continues into an angled run, or where a stair handrail levels out.
| FIXED CORNER
Use for all 90-degree turns. Set in place using a mallet.| | ADJ. VERTICAL CORNER
Use on inside corners around stairs and landings.
| ADJ. HORIZONTAL CORNER
Use for any level, horizontal turns.| | ADJ. 180 DEGREES
Use for handrail joints with 2 pivot points (e.g. on the inside
railing between 2 flights of stairs connected by a landing).

3. STRAIGHT SECTIONS CAN BE JOINED ANYWHERE – NOT JUST OVER A POST
Fixed straight splines are structural, so the handrail can break anywhere along sections of horizontal railing.
Installation is simpler − with less cutting & measuring − since the handrail doesn’t have to break over a post.
THE BEST METHOD for installing the handrail is starting at one end of your project & working around your railing, adding splines at each corner, angle & handrail joint. See examples of spline locations below.

IMPORTANT: Posts should be installed first BEFORE the handrail. After the handrail is mounted, install cable runs.

THINGS TO KNOW BEFORE INSTALLING A HANDRAIL

1. POSTS SHOULD BE INSTALLED FIRST before attaching your handrail.
2. HANDRAIL CAN BE CUT DOWN designed to be cut down in the field and joined using internal splines. Once installed, splines are concealed giving your handrail a clean, continuous look free of brackets or cover plates.
3. HANDRAIL JOINTS DO NOT NEED TO BREAK OVER A POST because the internal splines are structural. This makes it easier to plan out your post placement and allows for longer, continuous spans with fewer intermediate posts.
4. SPLINES SHOULD BE USED AT CORNERS & ENDS of handrail sections. We recommend you start at one end of your project and work your way around, adding splines at each corner/angle and end of the handrail sections.
5. USE A MITER SAW AND NON-FERROUS METAL CUTTING BLADE for any custom cut length. Use painter’s tape when cutting through the handrail to minimize chipping. Before joining your cut sections of the handrail, file away any burrs. A clean channel will allow for a cleaner joint. Before removing the painter’s tape, spray your ends with touch-up spray to cover any blemishes.

SECURING SPLINES & HANDRAIL

1. CUTTING HANDRAIL PIECES
   PRO TIP: Use painter’s tape when cutting through a powder-coated handrail to minimize chipping.
   Before joining your cut sections of the handrail, file away any burrs. A clean channel will allow for a cleaner joint.
   PRO TIP: Before removing the painter’s tape, spray your ends with touch-up spray to cover any blemishes.

2. JOINING LEVEL STRAIGHT RUNS
   Piece together longer, level handrail sections using structural fixed straight splines A. Splines are tapered and will tighten up as they are inserted into the spline.
   NOTE: Structurally fixed splines do not need to be supported over a post!

3. JOINING LEVEL CORNER RUNS
   Use Delrin fixed corner splines B for all 90-degree turns. Set in place using a mallet. If necessary, use a file on the spline to ease installation.

4. ADJUSTABLE SPLINES FOR ANGLED JOINTS
   Use adjustable splines C, D, E, F at your angled transition joints. Set the angle of your adjustable spline with a T-bevel and lock it in place with a 3/16” Allen key.
   HANDRAIL BEVEL CUTS
   Use an angle finder to determine the pitch of your stairs and make the appropriate bevel cut for your handrail.
