3 pk. Window Box Mounting Bolts 3/8in. Dia. x 3.5in. Long with Lag Shields (Brick/Masonry)

Use in mounting Premier Composite Cellular PVC boxes to homes with brick or masonry siding. We suggest using one pack (3 bolts) for mounting boxes 24"-48" in length. Drilling directly into your solid brick, masonry or stone - insert the lag shield first, then mark and drill holes through the back of the box or cleat to match your lag shields in the wall. Washers on bolt heads are not needed nor included.
