Technician Note
A take-up reel should only be used on systems designed for that style of edge connection. For fail-safe sensing edges, coil cords are generally the safer and recommended connection method.
Before Ordering
- Confirm the existing reel is 2 wire.
- Confirm the door travel does not exceed the 20 ft reel length.
- Inspect mounting location and cable path for rubbing or sharp edges.
- Verify the edge type before replacing a coil cord with a reel.
- Test the edge after installation with the operator under normal control.
Professional Advisory
Because this part is connected to the door safety edge circuit, the repair should not be treated as simple accessory wiring. A qualified commercial door technician should handle uncertain or unsafe installations.

The 50106 is a 2-wire, 18 gauge take-up reel with a 20 ft length.
Can this be used with a fail-safe sensing edge?
Take-up reels are not recommended for fail-safe type edge applications. Use the connection method specified by the edge and operator manufacturer.
When should a take-up reel be replaced?
Replace it when the cable is frayed, will not retract correctly, has broken conductors, or no longer keeps the moving wire under control.
Does the reel come with the sensing edge?
This product is the take-up reel only. Match it with the correct sensing edge, junction box, and operator wiring setup for the door.
