Bolt Down Bracket System #UL-BDBS
Manufactured by New England Arbors

 

If you are mounting your pergola to a wood deck or cement patio, the Pergola Bolt-Down Bracket System makes it easy! Simply measure your footprint and bolt the brackets into place. Insert 4 in. x 4 in. pressure treated wood posts (purchase separately) into the brackets and screw them in place. You will need to secure wood shims onto the side of the pressure treated 4x4 to ensure that when you slide the 5x5 vinyl post over top that the fit is secure and snug. Once you slide your pergola posts over the wood posts you then screw the pergola posts into the wood with the provided stainless steel self-tapping screws. The result is a lasting installation that is safe and rigid. This mounting system was specifically designed New England Arbors brand Pergola’s. For Attached Pergolas you will only need the two pack mounting system, however, for Freestanding Pergolas with four posts you will require the four-pack.
