The LiftMaster 655302 Edge Pneumatic 2‑Wire TakeUp Reel is an OEM component used to connect a pneumatic sensing edge to a LiftMaster commercial door operator. Designed for rolling steel doors, grilles, and high‑lift sectional doors, the spring‑return reel manages the moving connection between the bottom bar safety edge and the header, keeping the run clean as the door travels while delivering a simple 2‑wire contact to the operator’s safety input. When the air‑filled edge is compressed, the connected air switch is actuated and the reel assembly transmits the stop/reverse signal to help provide entrapment protection during closing.
This replacement take‑up reel is intended for systems that utilize a 2‑wire pneumatic edge circuit on LiftMaster commercial/industrial operators. No external power is required; it provides a dry contact closure to the control board’s edge terminals. Typical installation places the reel near the door header or jamb, with the airline routed from the bottom edge to the reel and the two conductors landed on the operator’s designated safety edge input per the operator manual. For operators that require monitored entrapment protection under UL 325, confirm whether a monitored pneumatic edge interface is needed for your specific model before commissioning. Use the 655302 as a direct replacement or upgrade in pneumatic safety edge applications where a reliable, tidy cable/airline management solution is required.
