For 6' Classic Style Stair Railing:

Prior to construction, check with your local regulatory agency for special

code requirements in your area. Structural support should come from

either the continuation of deck support posts that extend up through the deck

ﬂoor, railing posts that are bolted to the inside of the rim/outer joists or structural

post mounts. The post spacing will be less for angled rail applications. Always

measure prior to securing the posts when installing angled rail sections. Install

railing posts before deck boards are fastened to the joists.

The railing comes pre-drilled for attaching baluster connectors. Pre-drilling all

other screw holes is essential for successful rail installation. Do not over-tighten

screws. Read instructions completely to get an understanding of how the

product goes together and how each piece affects the others.

Step 1 Determine the number of railing posts needed for your deck. Post

spacing is either 6’ on center or 8’ on-center depending on the rail length

chosen. Example: A 12’ x 16’ deck attached to a building with a 4’ access

opening on one side will require a total of eight posts (ﬁg. 2).

Step 2 Install railing posts prior to installing deck boards. Cedar or pressuretreated pine 4x4 railing posts or a post mount provides the structural strength for the railing. The length of each post is determined by the total of the joist width (typically 7-1/4”) + decking thickness (1”) + railing height (36”) + spacing for post cap (1-1/4”) = 45-1/2”. Important: Do not notch the 4x4 railing posts. Notching will reduce the strength of the post and could result in railing collapse or failure (fig. 3).

Stair Railing Installation Instructions Equal spacing on both ends Step 1 Determine the number of stair railing posts needed for your deck. Post spacing is 6' on center. Step 2 Install stair railing posts prior to installing stair treads. Cedar or pressure-treated pine 4x4 railing posts or a post mount provides the structural strength for the stair railing. The length of each post is determined by the total of the stringer width + tread thickness + stair railing height + spacing for post cap.

Step 8 Place the proper rail bracket covers and stair brackets on the ends of the bottom rail. Pay particular attention to the brackets being used as they differ based on top/bottom rail and up/down angle. Prop the bottom rail between the posts on the stair treads (fig. 9). You may need to place equal shims between two stair tread noses to elevate the bottom rail. Check for requirements in your area.
