Slide assembly: QUIC-RELEASE slide assembly is ideal for use under bench or squad seats in ambulance and rescue vehicles. The fast acting latch system allows the cylinder to be pulled partially out for recharging or all the way out for replacement. The 2-part assembly is made of 12-gauge zinc-plated steel and measures 50" long or 9-1/4" wide x 1-1/8" high. Use with either model QR-M-2 or QR-MV brackets.
