LiftMaster L505AL Monitored Large Profile Resistive Edge with Aluminum Channel, 5'

Protect vehicles, equipment and people with the LiftMaster L505AL Monitored Large Profile Resistive Edge — a dependable safety solution for commercial barrier arms and gate operators. This 5' monitored resistive edge combines a durable aluminum channel with TPE rubber to deliver a rugged contact surface that resists corrosion and softens impact, reducing downtime and maintenance costs. The large profile design provides a broader contact area for easier alignment and secure attachment, while the 1" x 1.8" profile keeps the edge compact enough for many installations.

Built to meet UL 325 safety standards and designed for vertical or horizontal mounting, the L505AL integrates seamlessly with access control, surveillance and security monitoring systems to ensure accurate detection and quick response. The monitored resistive circuitry reduces false trips and simplifies diagnostics for maintenance teams. Backed by a 2-year limited warranty and manufactured by LiftMaster, this resistive edge is ideal for parking facilities, gated communities, and industrial entrances where reliable barrier arm safety is required. Specify the L505AL for your next barrier project or contact our sales team to confirm compatibility with your gate operator.
