Installation Guide

Secure the bottom U-channel to the posts

using the supplied #10 x 2-1/2-in. self-drilling

screws, then remove the template.

Note: Using the Surface Mount Bracket

(SMB) requires pre-drilling the bottom

Symmetry bracket holes. Locate brackets

holes using a 1/8-in. bit, then remove the

brackets/bottom U-channel. Predrill a 1/8-

in. hole approximately 2-3/4-in. deep into

the post keeping the same angle as with the

brackets in place. Next countersink the 1/8-

in. holes using a 1/4-in. bit only to a depth

that pierces the steel SMB. This will allow

the screw to clear the steel without damage

to the threads. Re-position the brackets/

bottom U-channel and secure with the

supplied #10 x 2-1/2-in. screws. Do not

over tighten.

Secure crush block holder to U-channel with

two #8 x 1-in. self-drilling ﬂat head screws. Do

not over tighten.

Locate the Symmetry bottom line bracket

templates (included on the post sleeve

carton and inside the rail kit box). Using the

10FT/12FT punch-out, slide the template

over the assembled U-channel and bottom

line brackets.
