Poly 1×4 Dock Boards

Thru Flow Plastic Decking | 1×4 Poly Deck Boards

Upgrade your dock or pier with 1×4 Thru Flow Plastic Decking Boards—the perfect resurfacing solution for worn or weathered decking. These poly boards are built with reinforced plastic construction and feature thru-flow holes that allow wind, water, and light to pass through, improving safety and durability.

Each board measures 11-1/4″ x 48″ x 1″ and installs easily onto most dock frames or platforms.

Key Features:

• Reinforced plastic construction for durability

• Thru-flow surface improves drainage and resists wind uplift

• Anti-slip ribbed texture for added safety

• UV-resistant polymer protects against sun damage

Perfect for replacing old wood decking or building out a new system. Use with Patriot dock frames or retrofit onto your existing dock for a low-maintenance, high-performance decking surface.
