The LiftMaster S505AL Small Profile Monitored Resistive Safety Edge Kit gives your gate a professional entrapment protection solution built for UL 325 monitored operators. It helps prevent damage to your gate structure and reduces risk to vehicles and pedestrians by triggering a reverse command when the edge senses an obstruction.
Gate operators manufactured after 1/1/2016 require monitored safety protection at the open and closed positions. The S505AL sensing edge covers both swing and slide gate applications and supports placement where you need it most. You get a 5-foot small profile edge plus an aluminum retainer channel that mounts on the vertical face of the gate where it closes against another leaf or structure, or on the horizontal face at the bottom. The kit includes two end caps, one wired and one non-wired, for a clean finish.
You can hardwire the S505AL directly into the gate operator using the included 39-inch cable, or connect it to the transmitter in the LMWEKITU Monitored Wireless Edge Kit for a cleaner install with fewer exposed wires. When paired with a compatible LiftMaster UL 325 monitored operator, the edge sends a monitored signal that tells the gate to reverse direction on contact.
The S505AL is built for outdoor use with an IP65 rating and a wide temperature range, so it performs in heat, moisture, and changing weather. It is a cost-effective way to keep your gate system safe, compliant, and reliable.
