The Bulwark Riser is the bare-bones to the winch-operated functions of the Multy Rack. The Riser gets installed to the High Rack, and the Low Rack with durable 1/2” quick pins through the included Saddle Mounts.
There are preset length adjustment holes to fit almost an trucks box length.
The Bulwark Riser comes as multiple pieces. Two main rails pin into the bulwark riser's head piece, which is where the winch is mounted.
