STAIR RAILING INSTALLATION

Place a picket into both rails near the bottom post -

ensure that the picket is plumb and 4" or less from the

post. Starting from the bottom post, measure and cut the

end spacers then remove the picket (Fig. 1).

NOTE: At the bottom post, end spacer "a" will be shorter

than end spacer "b".

Temporarily move the bottom post and rails away from

the top post (Fig. 2). Install the end spacers followed by

pickets and stair spacers (step 2 of Picket Railing

Installation). Cut and install the last spacers flush with the

ends of rails. The last picket must also be 4" or less from

the top post (Fig. 3).

Follow all applicable building codes for stair post placement and

heights of rails above nose of stair treads. NOTE: Stair pickets

and spacers are different from regular pickets and spacers. For

United States stair railing installations, regular hand and base

rails are not International Code Council compliant for graspability.

Always use stair hand and base rail set for stair applications.

Place the bottom post back into position and ensure that

the rails are fully inserted into the SCs at the top post.

Secure the hand and base rails to the SCs at the top post

as shown in step 2. Fasten the bottom post to the landing

or last stair tread - ensure that the post is plumb.

Use Stair Connectors (SCs) at each post.

Drill 1/4" holes through the end caps and secure to the

backing plates with connector bolts. Position the base rail at

the required height above the nose of stair treads.

Position posts to meet base rail less than 8" above base.

Fasten the top post to the deck - ensure that the post is plumb.

Position and mark the location of the bottom post on landing or on

the last stair tread - do NOT secure yet.

With the base rail still in position, place the SCs on the posts to align

with the base rail. Remove the base rail and mark the locations of

the SCs on the posts. Drill 7/32" pilot holes into the posts and use the

flat head screws to attach bottom SCs to the posts.

Measure and cut the base rail to fit between the end caps.

Cut the handrail to the same length as the base rail and fit

the SCs onto the handrail. Use two stair pickets to

position the handrail. Mark the locations of the SCs on the

posts. Remove the handrail from position and the SCs from the

handrail. Drill 7/32" pilot holes into the posts and use the flat head

screws to attach the SCs to the posts. Temporarily move the

bottom post to place the hand and base rails into the SCs.

Secure the SCs to the rails at the bottom post only.

PRO TIP: To ensure equal spacing at each post, cut the first

and last spacers in the hand and base rails to a length that

ensures equal spacing between the end pickets and the posts.
