Rotary FC5708-2 D-Shaped 2-Port Air Lock Cylinder for 4 Post Lifts
This D-shaped air cylinder mounts on the inside of the cross rail on Rotary 4-post lifts and pulls the safety locks open when air pressure is applied. It has two threaded ports on the flat side of the cylinder housing. Rotary produced both older and newer style D-shaped cylinders – verify your model is listed below and that your cylinder has two air ports before ordering.
