Collection: L4 Aluminum Dock System

Adaptive 

The L4 can be adapted to multiple waterfront environments, from shallow to deep water, to rocky, sandy or marshy bottoms, to low or highly sloped shorelines. 

Balanced high performance

The L4 gains its high-strength from marine-grade aluminum welded assemblies balanced with bolted multi-point joints to create a more durable high-performing flexible dock structure. 

Multi-Functional Modular Dock Technology

Designed with form and function the L4’s modular dock technology can be set up into multiple configurations to easily design a docking system unique to the owner’s waterfront needs.

Versatile design – Bolt on Slide in

With its unique fastening system, the L4 saves assembly time as floats are simply through bolted on to the sub-frame cross bracing. Likewise, decking panels can be quickly slid into the deck support of the chassis’s aluminum extrusion.

Solid engineering

Seaco’s engineered bolted assemblies make for consistent frame squareness throughout all modular frame sizes. Standard dock frame sizes are available in
4 and 6 foot widths and any length you want. No-Flex Hinges lock for a continuous rigid dock structure.

Good for the environment

Seaco cedar drop in deck panels are manufactured from responsibly harvested second growth timber. Aluminum is easily repaired and, at the end of its service cycle, can be recycled with less harm to the environment.

Lasting value

The combination of marine grade extruded aluminum framing and the drop in place aluminum “SeacoNut®” fastening system make for a corrosion free installation. Built to last, the L4 greatly reduces maintenance and service costs.
