The LiftMaster 50106 Reel Take-Up is a genuine replacement accessory engineered to manage the traveling cord for a door-mounted safety edge on commercial and industrial overhead doors. Featuring a 2-conductor 18 AWG lead with 20 ft of travel, it provides a tidy, retractable connection between a bottom-sensing edge and the operator’s safety input, helping maintain consistent contact as the door opens and closes. It’s commonly used on sectional and rolling steel doors where a wired edge is preferred, delivering reliable cable management for smoother operation and reduced cord wear.
This 2-wire configuration is intended for non-monitored sensing edge circuits; always verify that your LiftMaster commercial door operator supports a 2-wire edge input and meets local code requirements. Installation typically involves mounting the take-up reel to the jamb or end plate, routing the cord to the bottom edge, and terminating the two conductors at the operator’s edge terminals per the operator and edge manufacturer instructions. After wiring, test the door to ensure proper stop/reversal per UL 325 procedures. For facilities requiring monitored edges, use an approved monitored interface or a monitored edge solution as specified by LiftMaster. Suitable for many commercial/residential light-duty applications where a wired safety edge is used and a 20 ft cord travel is appropriate.
