LS4 Anodized Aluminum Dock Frames with Leg Frame - No Decking
The LS4 Anodized Aluminum Dock Frame System is a premium residential dock solution engineered for exceptional strength, long-term durability, and true modular flexibility. Each LS4 dock frame is built around a full 4" anodized aluminum box frame, providing nearly twice the aluminum content of standard F-channel dock frames. The result is a noticeably stiffer, more stable structural platform that maintains its alignment and integrity over time—giving you a solid foundation for the decking of your choice.
Anodized, fluted tubular stringers and an integrated accessory track system form the foundation of the LS4 dock frame, providing exceptional strength and versatility without locking you into a specific decking option. The heavy-duty frame is engineered with 16" on-center support, allowing you to install a wide range of decking materials, including pressure-treated lumber, cedar, composite decking, PVC decking, or Thru-Flow panels, depending on your preference and budget.

Effortless Setup & Custom Layouts
Each LS4 dock frame is designed for simple, efficient installation. After selecting the appropriate leg posts (sold separately) based on your water depth, all frame-specific hardware is included. Unlike traditional docks that require strict end-to-end alignment, LS4 frames allow connectors and leg sockets to be installed along the sides of the dock. This makes building wide platforms and custom layouts significantly easier.
Frames can be leveled individually as you build, eliminating the need to align and level multiple frames at once. This modular approach saves time and reduces installation frustration.
