Bolting the Frame to your Houseboat or Yacht
3/8" Stainless Steel Carriage Bolts are included in the kit. There are 2 rows of 6 forward mounting holes in the Frame to accommodate the height of all swim platform steps, and 8 downward holes (hidden under the rail tubes in the right photo). Any combination of 4 forward, 4 down, or 2 each direction is all that is needed. See the Instructions for recommendations.
When the Rails are tilted up, the gas-shock lift arms hold the Rails upright. The basic kit comes with 1 lift arm. You can get a second as an upgrade if you get the heavy duty Rails and want more lifting power.
For additional safety when tilted up, ALWAYS hook the cable on the cross-member as shown below, and snug it up with the Power-IN button. This will prevent unintentionally lowering the Rails which could hurt someone.
