MaxDock MLC009-12 - 9' to 12' Adjustable MaxLoc Dock Cross arm Assembly

The MaxLoc adjustable T&L cross arm assembly is easy to install and adjust. This is one of the strongest cross arms for freestanding docks on the market today.  Constructed of a 2"x4" aluminum extrusion it features a solid anodized aluminum end clamp and one pre-attached stringer connection plate as well as a bracket for directional change in support configuration. The end clamp tightens around a 2" OD dock post with the use of a 5/16" hex wrench. Once tightened, this cross arm will not move!



  • VERY STRONG 2" x 4" Aluminum Extrusion Crossmember
  • Post clamps provide 360 Degree Even pressure
  • End clamps tighten around a 2" OD dock post with the use of a 5/16" hex wrench
  • Once tightened, this cross-arm will not move!
  • Pre-Attached Aluminum Stringer Plates



The MaxLoc complete cross member makes dock height adjustment simple and quick. Only requiring a single hex wrench to adjust the height while providing a secure fit. Custom support widths are available and can accommodate up to a 30' wide platform.


To create a complete dock support, you will need to add the following;

  • One - MaxLoc 9'-12' adjustable cross-arm assembly with integrated cross-arm clamps and stringer brackets
  • Two - 2" OD vertical dock posts (choose the correct length for your water depth)
  • Two - standard base pads, large base pads or dock post augers



Dock Base PadStandard 7.5" x 7.5" aluminum bottom plates work well in sand and other solid lake bottoms. Not recommended for extremely deep mud or muck.



Large Dock Base PadLarge 12" x 12" aluminum bottom plates provide a larger footprint for the leg and works better in area with softer lake bottoms, may not work well in extremely deep mud or muck.



Dock AugerAluminum Dock Augers are recommended from supports that will have boats or watercraft tied to it. Augers make installing the support more work than using just bottom plates. The auger helps to anchor the dock to the lake bottom. You can also use a combination of base pad and auger for maximum support.

For single section runs in water depths exceeding 5' or very soft lake bottom conditions, you may want to consider the X-Brace add-on kit for increased stability and section sway reduction.
