SELECT RAILING
Attaching Brackets to Rails
5a. Position brackets on each end of TOP RAIL on the 
same side as baluster holes. Attach brackets using 
three #8-18 x 1" self-drilling 
screws (provided).
5b. Position brackets on each end of BOTTOM RAIL on 
the OPPOSITE SIDE of the baluster holes. Attach 
brackets using three #8-18 x 1" self-drilling screws 
(provided).
Assembling Railing Section
6a. On a clean fl at surface lay bottom railing on its side. 
Make sure to allow enough room for installation 
of balusters and top rail. Place a scrap piece of 
1" decking board running parallel to bottom rail for 
support when installing balusters.
6b. Insert balusters into bottom rail slots until balusters 
are fully seated.
6c. Attach top rail to 
balusters, feeding each 
baluster into required 
slots. Start on one end 
and work towards the 
other.
6d.  To help temporarily 
secure the railing 
section together, place a 
ratchet strap around the 
top and bottom rail and 
tighten until snug. DO 
NOT OVERTIGHTEN 
AS YOU CAN BEND 
THE RAILING.
Installing Railing 
Section to Posts
7a.  Using scrap material (i.e. 
2 x 4s, decking boards, 
etc.) cut at least three 
support blocks at 3-3/4"
in height. Place one 
each on decking surface 
beside each post and 
one near center of span.
7b. Lift secured railing 
section up, and 
CENTER this section in 
between the spanned 
posts on pre-positioned 
support blocks.
NOTE: To help stabilize 
railing section use a quick-
grip clamp (or other type of 
clamp) and clamp the fi rst baluster to post sleeve. 
(DO NOT OVERTIGHTEN CLAMP.)
7c.   Install both bottom and top brackets on each 
side to post using two #8-10 x 2" wood screws 
(provided). For best results, set drill to low speed 
when installing these screws.
