The LiftMaster 658206 Treadle Kit Pneumatic N4/12, 10 ft, is a vehicle-activated air hose switch designed to trigger LiftMaster commercial gate, barrier arm, and door operators when a tire rolls over the hose. Ideal for free-exit, open, or reverse commands depending on how it is wired to the control board, this replacement treadle kit uses pneumatic actuation to send a momentary signal to compatible operators. With a 10 ft hose, it provides a simple, rugged alternative to loop detectors for drive-up activation in parking, industrial, and commercial applications.
The N4/12 designation indicates a sealed, weather- and dust-resistant switch enclosure commonly used in demanding outdoor environments, supporting reliable performance in rain, dust, and washdown conditions. The pneumatic design requires no power at the treadle itself and connects to the operator’s standard control input terminals. Installation typically involves mounting the air switch enclosure near the operator, routing and securing the hose across the approach path, and wiring into the open/exit input as specified by the operator’s manual. For safety, position the hose to avoid pedestrian trip zones and pair the system with UL 325–compliant monitored entrapment protection where required. This pneumatic treadle kit is suitable for new installs, upgrades, or as a universal replacement part on LiftMaster and many other commercial operators that accept a momentary contact input.
