1.

Prepare all posts and mounting surfaces before installation.

2.

Temporarily secure a plank on the noses of the stairs between the posts onto which you are 
installing the stair rail. (Fig. 1) The thickness of the plank will determine the space between the 
stairs and the bottom rail.

Place the bottom rail, baluster holes facing up, on the plank and slide the rail up or down until 
the baluster hole spacing is even on each end.

Tip:

 Clamp rail in place as shown in Fig. 2 to assist in assembly.

Measure the distance from post to the first baluster hole and ensure spacing of at least 1¾" to 
allow for bracket fit (Fig. 3).

Trace the post onto the rail and mark

" short at each end to allow for expansion (Fig. 4).

Cut the rail to fit.

Tip:

 If using a power saw, a carbide tip blade of at least 60 teeth is recommended. 

3.

Slide a bracket onto each end of the bottom rail (Fig. 5). Position the rail in place and slide the 
brackets against the mounting surface. Check for proper fit and attach to the post using the 
mounting hardware. 

Pre-drill using a

to secure the rail in place (Fig. 5).
