Deck2Wall Spacer, Decking Hardware

Designed to provide airspace easily and efficiently between buildings and deck ledgers, stair stringers, shade structures, railing posts, fence posts, and more to help prevent rot. Deck2Wall Spacers are easy to install. Simply fasten the spacer to the ledger with properly sized screws or nails through the attachment holes before bolting the ledger to the structure. The large diameter provides a greater bearing surface than standard washers.
