INSTALLATION REQUIREMENTS

•  A fixed dock is ideally suited for water depths under 1.3 m (4 ft).  

•  A fixed dock is not made to withstand pressure or tension caused by moored boats in agitated waters. We recommend 

separated mooring systems; deadman blocks, chains and mooring buoys.

•  In rough condition areas, or if piles are used to their full lengths, you should increase the dock's stability by adding 

diagonal braces to the posts (item # 22034).

•  Have two strong adults to assemble frame. Install decking while on solid ground, then bring dock to water to install on piles.  

SAFETY FIRST

Our MULTINAUTIC® team of professionals has designed and engineered the best lightweight aluminum dock available. 

Please read these instructions before assembling your new dock, to ensure that assembly is done safely and correctly. 

•  All bolts and nuts are tightened securely before using your new dock.

• 

DO NOT

 

modify this dock system, as alterations or welding can weaken the structure and will void the warranty.

•  Always wear personal safety protection such as safety glasses, work gloves and boots.

•  Keep children and pets clear of work area during assembly.

•  Weight capacity of this dock structure will not support vehicles of any kind and is limited to 4 people or 363 kg (800 lbs). 

• 

DO NOT

 

use corded electrical tools in or near water.

MAINTENANCE AND STORAGE

ALUMINUM FRAME: There is no maintenance required on the aluminum frame itself.  Due to air and water exposure, a 

light tarnish may appear. Simply rub the frame with a Scotch Brite™ style pad to remove light scratches, though tarnish 

or light scratches will not affect the strength or integrity of the dock.

WOOD DECKING: –Important– Your aluminum frames should never come in contact with green treated wood. We highly 

recommend cedar, which is light and maintenance-free, and that you refer to your wood supplier if you want to apply a 

protective product. 

Never leave post docks in the water in wintertime because of ice movements.  When storing the docks, leave the decking in 

the aluminum structure.  You may store them flat (upside down to prevent fading under the sun) or straight on their sides.
