Patriot Docks Poly 4x4 Dock Panels (10851)

Patriot Docks Poly Decking Panels – Slip-Resistant, No-Maintenance Dock Surface Stay cool, stay safe, and skip the upkeep. The Patriot Docks Poly Decking Panels offer a superior, long-lasting surface for your dock—designed to withstand the elements while keeping your dock cool, dry, and secure. Available in Gray or Tan, these 47 3/8" x 47 7/8" x 1" panels feature a thru-flow surface that allows water and wind to pass through, reducing heat buildup and preventing lift in rough conditions. What truly sets these panels apart is their aluminum-reinforced core—a major upgrade over standard plastic dock boards. This internal bracing increases strength, rigidity, and longevity, so you get a surface that won’t sag, flex, or fade over time.
