Round Deck To Wall Spacer 3/8 in. (10-Pack)

Protect your deck ledger and home siding from moisture buildup and wood rot with these precision-molded spacers. Each 3/8-inch thick, round spacer maintains a consistent air gap between the deck ledger board and the house, allowing water and debris to drain freely while promoting circulation and rapid drying. Crafted from glass-filled polypropylene, they offer excellent strength, impact resistance, and long-term durability—even in harsh outdoor environments.

Easy to install and compatible with standard structural wood screws, this 10-pack ensures uniform spacing and reliable performance for both new deck builds and retrofit applications. By preventing direct contact between wood surfaces, these spacers play a crucial role in extending the life of your deck connection and safeguarding against costly rot repairs.
