SELECT RAILING
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" (95 
mm) 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 
first 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.
