ShoreMaster pontoon lift racks feature a set of four that mount to the lift rack and adjust horizontally. These pontoon racks work great for ShoreMaster lifts with straight rack cradle designs. They are manufactured out of marine-grade aluminum and come with stainless steel hardware. This model is designed for ShoreMaster Straight Rack lift models. The straight Rack design is commonly found on older style Cantilever and Vertical ShoreMaster hoists. Straight Rack frame designs utilize a zero degree tube bend on front and rear rack beam.
