Rail-Lok™ Snapless Cover System

Snapless Trailerable Pontoon Covers

The Rail-Lok system is the first towable pontoon cover available in the market. This custom-fit pontoon cover system features unique fasteners that lock into the receiver slot under the middle rail extrusion on the pontoon’s fence. These patent pending fasteners are engineered for simple use.

Spaced strategically around the edges of the cover, the system delivers a tight and secure locked-in cover eliminating hard-touse snaps. Taking into consideration the variation in design of pontoon rails, Dowco has designed two versions of Rail-Lok, PX and HC.


  • Quick & easy to fasten into the custom rail

  • No time spent lining up unsightly snaps.

  • Safe & secure fastening
  • When engaged, the system locks the cover firmly in place

  • Removing the cover is just as easy and can be removed in record time
