Top Image for Hidden Dock Supports

DOCK SYSTEMS : Support Options

With 3 styles of supports you can design almost any layout.

Post Heights

We recommend you place your dock 16" above the surface of the water.
For Standard Supports remember to include all 4 measurements depicted below to select the proper post length.
The Hidden Supports are designed so that the water depth is the only measurement needed to order the correct support.

Bottom Conditions

Different types of lake bottoms require different types of support.
Use the diagram below to decide which Bottom Plate or Auger is right for you. In hard sand or gravel you can use either a Hidden Support or Standard Support Assembly with any type of auger or bottom plate.
In mud or silt the use of Standard Support Assemblies may be necessary to allow
for deep and secure augering of the posts.
