Bolt Down Bracket System for Pergolas
3
Measure and mark out the location of the bolt down brackets using
string or chalk line. Diagonal distances must be the same to ensure a
square installation. Adjust string lines accordingly. The inside corner of
the string lines will be the corner of the bottom flange of the bolt down
bracket.
Mark out the hole locations of bolt down brackets.
IF MOUNTING TO CONCRETE SURFACE, proceed to step 3
IF MOUNTING TO WOOD OR COMPOSITE DECKING, proceed to step 4
Using a 3/16” m (0.48 cm) masonry drill bit, drill 3” (7.6 cm) deep holes to
allow installation of 2 3/4” (7 cm) concrete screws (purchased separately)
Proceed to install three 2 3/4” (7 cm) concrete screws into the bottom
base of each of the bolt down bracket.
Proceed to step 6
Please Note:
Concrete patios generally have sloped surface for water run-off. If this
is
the case, when you secure the bolt down bracket to the concrete, the
bracket may be at an angle. This can be corrected for level using
galvanized steel washers (not provided), acting as shims underneath the
base to level - VERY IMPORTANT OR PERGOLA BEAMS AND RAFTERS
WILL NOT BE LEVEL.
Using a 3/16” (0.48 cm) wood drill bit, drill the three holes through
the wood deck. Obtain a ‘blocking board’ such as a piece of 2x6 (5 cm
x 15 cm) x 6” (15 cm) long. Using the bolt down bracket as a template,
mark and drill three holes through the blocking board. The blocking
board will go underneath the deck and will distribute the
compression force created by the fasteners (bolt and nuts)

The following steps use a traditional 4-column pergola as an example.
