These Cams are made of adjustable unistrut and a metal cam to allow maximum adjust ability. You would install one of these at each landing you have a F-4 Switch at so that the F-4 Contacts are both closed when the cam presses up against the F-4. The standard length of the Stationary Cams allows for mounting 24"-30" from the rail. If other than standard, please specify mounting distance and cam length required in the checkout page comments.

These can be used for Switch Type Elevator Leveling Systems or with Floor Switches to Level the Elevator. Other sizes are available upon request.
