 Railing 6 and 8 ft. Installation Instructions
Cover 4x4 posts or Fiberon surface mount 
bracket with post sleeve and verify spacing. 
posts should be plumb in both directions. 
Place post sleeve base moulding over post 
sleeve and slide it down to the deck surface.

Note: Make sure posts are plumb and 
level prior to installing the railing.
Pre-drill holes using a 5/32 in. bit (bracket and 
rail shown for clarity). 
Note: Using an extended drill bit is 
recommended to prevent damage to the rail, 
and allow a more perpendicular driving angle.
Note: When using surface mount brackets, 
use titanium or cobalt bits only. Pre-drill the 
post sleeve and steel bracket with a 1/4 in. bit 
until the steel is penetrated. This will allow the 
bracket screws to engage the wood 4x4 and 
pull the rail snuggly to the post. Do not over 
tighten.
Pre-drill holes using a 5/32 in. bit (bracket 
shown for clarity).
Secure the bracket with supplied 1 in. 
screws. Do not over tighten.
Support the bottom rail level and at the desired 
height using the adjustable crush block. Using 
a level, center the rail on the posts, then mark 
the bracket hole locations.
Flip the bottom rail so that the pre-routed 
holes are facing downward. Center the 
bracket at each end of the bottom rail. To 
help ensure a snug installation, allow 1/32 in. 
to 1/16 in. clearance between the bracket 
“wing” and end of rail. Mark hole locations.

Measure the distance between posts. 
Center the bottom rail hole pattern within 
this dimension and cut to length. Place 
between posts checking for snug t. Align 
top and bottom rail holes and mark the cut 
length on the top rail.

To assemble the adjustable crush block, 
push the center up through the base, making 
sure that the compression wings align with 
the ridges inside the core. Insert until the rst 
“click” is heard. If the center is inserted too 
far, it can be pushed through completely.
Remove the rail from between the posts. 
Find the center point (or 1/3 and 2/3 point 
if 2 adjustable crush blocks are provided) 
on the bottom underside of the bottom rail. 
Pre-drill a hole with a 5/32 in. bit. Secure the 
adjustable crush block with the supplied 
3/4 in. screws. Do not over tighten.
