The Under Dock Support with A-Frame Stance is hidden from the top of the dock and provides great stability.  The deeper the water, the wider the stance which creates a more stable dock in comparison to traditional H-Frame style supports.  Under dock supports create a more aesthetically pleasing look, when installed there are no posts above the walking surface as you find with other support styles.



  • Adjustable from 9' - 12'
  • Stand Ends with Stringer Brackets (2)
  • 63" Center Crossmember Section - (2)

  • 7" x 12" Angled Base Pad - (2)
  • 7" x 7" Standard Base Pad (center) - (1)



  • STRINGER BRACKETS - This is where your dockside stringer will sit and has holes to fasten the dock section to the support.
  • SPACER - This is used to place under the side stringer of a dock if it happens to line up over the Extension tube so the dock remains level. This spacer can be moved across the Extension tube anywhere it needs to be located.
  • CENTER CROSSMEMBER - This portion of the support uses the same extrusion as the Stand Ends and work as the main central support for the stand.
  • EXTENSION TUBES - These tubes slide into the Center Crossmember and Stand Ends and allow for the width adjustment. A simple 1/2" stainless bolt and brass nut are used on the Center Crossmember and Stand End to tighten up the Extension Tube at a given width.
  • STAND END - These are the two angled ends of your support and included a 45° brace and the Stringer Bracket. This assembly also has two 1/2" stainless bolt and brass nut Leg and Extension Tube with adjusters.
  • LEG POST AND BASE PAD - Included, but not pictured.



    STANDARD 9' - 12' MAXSTAND SUPPORT - This option includes the stand itself with 30" legs, three 36" telescoping posts, center support and three base pads (2 outside and 1 center). The combination of the 30" legs and the standard 36" posts give this stand 56" of vertical height. Longer legs can be added.
    "SHORTY" 9' - 12' MAXSTAND SUPPORT - The ''Shorty'' is used for shallow water applications and the stand comes with 20" legs, 18" posts, three base pads and also includes center support. The combination of the 20" legs and the 18" posts give this stand a 38" max height. The lowest it can get is 22" off the lake bottom. If you need shorter supports, you can bury the feet to reduce the height or use a MaxLoc or Traditional Support instead.
    ''T'' & ''L'' 9' - 12' MAXSTAND SUPPORT - This support is designed to create a ''T'' or an ''L'' design with your platform. One end of the support has a standard leg and the other end is set up to attach directly to the cross member of the last MaxStand and use it to support that end. This stand includes the TL stand with 30" leg(1), center support, two 36" leg posts, two base pads and the T&L hardware.
