Installing a Pergola on Trex Decking:
» Keep in mind if you are planning to install a Trex
® 
Pergola
™
 on your deck, you will need access to the 
underside of the deck. Trex Pergola mounts with a 
10" x 10" (254 mm x 254 mm) aluminum plate on the 
underside of the deck, creating a clamping effect on 
both the top and bottom of the deck for maximum 
strength. If installed, water barriers and any under 
deck coverings will have to be removed to properly 
install the pergola posts.
» You need to consider the location of your pergola 
posts in respect to joists. However, you do not have 
to mount your plates between joists. It is possible to 
place blocks on the bottom of the joists and mount 
the Trex Pergola brackets through the blocks.
