The Dura-LITE™ aluminum dock design combines form with function in one of the strongest aluminum dock frames available in the market.

Everything about the Dura-LITE™ is designed to be easy, low maintenance, strong, and more attractive. With an 85lb (4×10) frame, and the option to have removable deck panels for most of our decking products, installation can be done by one or two people. This is our premium dock for use in medium to large water bodies, or for bigger recreational boats. With clean 6” sides and a heavy duty anti-slip reveal on the top edges, aluminum frames the picture of your choice, rustic or modern decking. We offer choices of cedar, solid board HDPE lumber, fiberglass reinforced decking.

Dura-LITE™ aluminum docks are available in both floating and stationary configurations, including roller docks. Dura-LITE™ docks are designed to be temporary, but are suitable for use as permanent structure if ice is not present and local building codes permit.

Made in Maine for the harsh conditions of big lakes, the Dura-LITE™ superior strength comes from heavy duty 6″ tubular frames, offering maximum resistance to flexing from vertical load and twisting forces. Compare this to channel and truss frame style docks which have very little resistance to twisting forces.

Adding sections to stationary Dura-LITE™ docks is a snap with our snap-on connector J brackets. Some basic tools are required as we want you to spend less time installing your dock, and more time enjoying it. Snap-on J brackets let you add sections anywhere you want. If you decide to reconfigure your dock, J brackets can be pried loose with a large flat screwdriver, and re-used in the new location. Stationary sizes include: 4’x10’, 4’x12’, 4’x16’, 6’x8’, and 6’x10’.

Dura-LITE™ stationary Aluminum Docks employ the use of rugged 1-½” schedule 40 galvanized or aluminum pipe for legs. This keeps cost down, and pipe allows the installer to drive the legs into the lake bed, which secures the dock and makes it more suitable for tying boats. The basic frame has all the bracing you need to take you up to 3-4ft of water depth. In 4-8ft of water, we recommend using either our Hook and Lock braces to increase strength and stability.

To avoid confusion if buying pipe that fits in the pipe sockets at your local pipe supplier, the industry standard calls the pipe size as 1.5″ schedule 40 but the O.D. is actually 1 7/8″.

The simplicity of adding on continues with more snap on accessories, including vertical and horizontal bumpers, benches, ladders, railings, and mooring whips. These snap-on accessories secure to small linear tracks on the top and bottom of the dock frame. The thin hook shaped groove, hardly noticeable from the top edge, is uniquely designed to secure accessories, while remaining too small to capture large pieces of debris.

Dura-LITE™ docks are uniquely designed with a proven system to hold removable composite decking panels flat, without compromising the ease of removal. Framing is standard at 16″O.C. to accommodate almost any composite. With over 60 composite products on the market, we understand the behaviors and potential for curling. Some want to curl up, some curl down. We have a latching system for each type to ensure your panels remain flat for the lifetime of your decking. Hidden fasteners hold decking from the underside, so you can enjoy a cleaner look on the top side.

Dura-LITE™ stationary docks employ the use of rugged 1-1/2″ SCH. 40 galvanized or aluminum pipe for legs. This keeps cost down, and pipe allows the installer to drive the legs into the lake bed, which secures the dock and makes it more suitable for tying boats. The basic frame has all the strength you need to take you up to 3-4ft of water depth. In 4-10ft of water, we recommend using our Hook & Lock Braces to increase strength and stability. In water deeper than 10’, consult one of our professionals for advice, as a floating configuration may be more suitable. Dura-LITE™ docks can also be set up to stand on feet for temporary tie-up, general recreation, or use of kayaks, canoes and rowboats. If tie-up of large watercrafts is desired, but driving pipe is not possible, consult one of our professionals for advice on other anchoring methods.

Mooring whips on Dura-LITE™

Here at Great Northern Docks, we often suggest using mooring whips to keep your boat held off the dock. The boat may bump the dock on occasion but the whips prevent constant bumping. Spring lines are used to keep the boat in line with the dock so the whips remain perpendicular to the edge. Holding the boat off the edge of the dock will protect both the dock and the boat.

Although whips do come with their own base for mounting to the decking, we make a base (Goose Neck Whip Brackets) that can attach to the side of our docks to work as an alternative base for the whips we sell.
