Solid brass wood deck anchors may be used to anchor covers to wood decks capable of supporting the anchor. It is up to the installer to determine if the decking is sufficient thickness and strength to support the cover tension and the attachment of the anchor. Anchors should be countersunk into decking by drilling two holes in the wood. First a 2" x 1/8" countersink for the top flange. Second, a 3/4" hole to accept the body of the anchor itself using a conventional drill bit. A 2" Forstner Bit is recommended for quick drilling of the shallow countersink hole.
