The LiftMaster OES-4504 Edge Channel is an OEM mounting channel designed for installing a monitored safety edge along the bottom of a sectional overhead door. Built for sectional doors with a 1-3/4 x 1-3/4 bottom rail, this 16 ft channel provides a straight, secure track for the LiftMaster OES edge assembly, helping ensure consistent contact and reliable activation across the full door width. When paired with a compatible monitored sensing edge and a LiftMaster commercial door operator that supports monitored edge inputs, the OES-4504 forms part of an entrapment protection solution that supports UL 325 requirements for commercial and industrial applications.
Ideal for new installations or replacement/retrofit projects, the OES-4504 helps simplify edge alignment and durability, especially in high-cycle facilities. Install by fastening the channel to the door’s bottom member and seating the appropriate LiftMaster OES sensing edge per the manufacturer’s instructions, then route and connect the edge lead to the operator’s monitored edge terminals. After installation, perform functional testing of the safety edge and operator to verify proper operation and compliance with site safety procedures. This edge channel is commonly used with LiftMaster sectional door operators in warehouses, logistics, retail back-of-house, and other commercial settings where a monitored bottom edge is required.
