Seco-Larm SM-226LQ Overhead Door Magnetic Contact

Overview

The Seco-Larm SM-226LQ is a magnetic contact engineered for overhead doors and screens in both industrial and residential applications where a wide gap is present. The switch is housed in a curved, low-profile cast-aluminum enclosure designed for surface mounting directly on the garage floor, durable enough to withstand heavy vehicles passing over it. The magnet is enclosed in a gray ABS case mounted on an L-shaped bracket, and the 24" (61cm) wire leads are protected by armored stainless-steel cable for maximum security. The SM-226LQ is adjustable to fit most door-channel widths and includes a mounting bracket.
