This is the channel only and does not come with the mounting blocks. The Ferno 185 Series StatTrac Cot Fastening System is designed to secure a Ferno cot or transporter inside a ground-based ambulance. The Ferno Stat Trac Cot Fastening System is a straight-in-track design that eliminates cot drift and the need to steer the cot in, minimizing operator strain on angled surfaces. A single-hand release and wide-angle entrance guide provide quick and easy cot loading.
