LS4 Anodized Aluminum Dock Sections with Leg Frame
The LS4 Anodized Aluminum Dock System is a premium residential dock solution designed for exceptional strength, long-term durability, and true modular flexibility. Each LS4 dock section is built around a full 4" anodized aluminum box frame, providing nearly twice the aluminum content of standard F-channel docks. The result is a noticeably stiffer, more stable dock that feels solid underfoot and holds its shape over time.
Anodized, fluted tubular stringers and an integrated accessory track system make it easy to add or reposition dock accessories without drilling. This not only speeds up installation but also preserves a clean, professional look. Whether you’re building a straight dock run or a large platform, LS4 sections are engineered to go together easily while delivering structural performance typically found in heavier, commercial-style docks.

- 4 Available Section Sizes – 4' x 10', 5' x 10', 4' x 12' and 5' x 12'
- Integrated Accessory Track System – Mount cleats, bumpers, ladders, and accessories without drilling
- True Modular Design – Place leg pockets and section connectors at corners or along the sides

- DIY-Friendly Assembly – Designed for fast, straightforward installation and easy leveling
- Low Maintenance – No rot, warping, staining, or seasonal upkeep required
While the LS4 is an upgrade from entry-level aluminum dock sections, it offers significantly more metal and structural integrity per dollar. The thicker boxed frame with built-in accessory rail grooves adds strength even when no accessories are installed, and the integrated bracing provides excellent lateral stability in all directions. Combined with anodized aluminum decking that stays cooler in the sun and requires virtually no maintenance, the LS4 is an ideal choice for both first-time DIY installers and experienced dock owners.
Effortless Setup & Custom Layouts
Each LS4 dock section is designed for simple, efficient installation. After selecting the appropriate leg posts (sold separately) based on your water depth, all section-specific hardware is included. Unlike traditional docks that require strict end-to-end alignment, LS4 sections allow connectors and leg sockets to be installed along the sides of the dock. This makes building wide platforms and custom layouts significantly easier.
Sections can be leveled individually as you build, eliminating the need to align and level multiple sections at once. This modular approach saves time and reduces installation frustration.
