May be used in two different ways; as an OPEN only control (all LiftMaster operators) or as an OPEN/CLOSE control (only LiftMaster operators with types B2 and S2 control wiring). In the latter case pulling the cord will open a fully closed door close a fully opened door and reverse a closing door.
Pulling the cord whlie the door is opening will either have no effect (type B2 wiring) or will stop the door (Solid State Logic Control Board).
WARNING: When used on most industrial operators this control will not stop the door. Use another control that has a STOP button in conjunction with this control.

A brake band hold-down for a mechanical dock leveler includes a frictional brake that grabs the hold-down when the ramp is at the proper elevation.
If additional upward force (this can happen when trailers move up and down when trucks are loaded or unloaded) is applied to the ramp the frictional brake will give way just enough to accommodate the change.
This prevents the dock leveler ramp from being damaged.
IMPORTANT NOTE: The new safety reversing sensor brackets are only compatible with the new safety reversing sensors (041-0136) and are NOT compatible with older style safety reversing sensors.
