8.   Secure posts to panel with four #8-18 short 
self-tapping screws (provided) in each location.
9.   Attach shorter side of 
hinge to the gate.
NOTE: Refer to 
instructions included 
in hardware package. 
Be sure to use correct 
fasteners for aluminum. 
See chart below.
NOTE: Use of non-Trex hardware is not 
recommended and could result in serious 
injury or death.
10.  Place gate in opening on blocks. Sweep between 
bottom of gate and top of deck cannot exceed 
4" (102 mm) per IRC/IBC code regulations. Ensure 
bottom gate posts will be high enough to clear skirts 
on bottom of deck posts. 
11.   Make sure posts are plumb 
and gate is level. Attach 
longer side of hinges to 
post using appropriate 
hardware for type of post 
installed. Install hinge 
cover.
  NOTES: 
»  Both wood and 
aluminum screws are 
included in hardware kit. 
(Refer to chart under 
Step 9.) 
»  If using Trex Post Mounts with Post Sleeves, 
pre-drilling is required using 1/8" (3 mm) drill 
bit, as you must go through both aluminum 
sleeve and internal post.
12.   After determining location and height of hinge 
and hasp, install per 
instructions included with 
hardware kit.
13.   Ensure proper operation 
of gate. Hinge tension is 
adjustable (check hardware 
kit instructions for more 
detail).
14.  After gate installation, 
place blocks under gate 
for support. Use a rubber 
mallet to install cap onto 
gate post. Repeat for other 
gate post cap. Snap all 
hinge covers into place.
