LiftMaster 658206 Exterior Pneumatic Treadle Kit
The LiftMaster 658206 exterior pneumatic treadle kit is designed for vehicle activation at commercial doors and controlled access openings. When a vehicle drives over the hose, the air pulse operates the switch and sends a signal to the connected operator control circuit.
This kit is often selected where cutting a loop into pavement is not practical or where a simple above-ground vehicle treadle is preferred. It is not intended to replace monitored entrapment protection or pedestrian safety devices.
Compatibility and Application Notes
- Commonly used with compatible LiftMaster commercial door operators and control stations that accept a 2-wire switch input.
- May be used as an OPEN control on many operator setups when the input and control logic are correct.
- May be used as a SAFETY input on select older operator wiring types such as B2, C2, T, T1, or TS when the operator documentation allows it.
- Designed for vehicle-actuated applications using a pneumatic treadle hose.
- Not a complete safety system and not a replacement for photo eyes, sensing edges, or code-required monitored protection.

Technician Note
A pneumatic treadle should be positioned where only intended vehicles cross it. Poor hose placement can create nuisance operation, missed activation, or unsafe traffic flow around the door.
Before Ordering
- Confirm the operator input is suitable for a treadle switch signal.
- Confirm the application is vehicle activation, not pedestrian protection.
- Confirm the hose length and enclosure location work for the driveway or door approach.
- Confirm the site environment requires an outdoor-rated enclosure.
- Confirm required door safety devices remain installed and functional.
Professional Advisory
A qualified commercial door technician should verify the operator control wiring before connecting a treadle kit. Do not wire a treadle in a way that bypasses monitored safety protection or creates automatic movement without proper safeguards.
Product Questions & Answers
What comes with the 658206 treadle kit?
The kit includes the outdoor NEMA 4/12 enclosure, 10 ft. signal hose, outdoor air switch, and hose plug.
Does this pneumatic treadle need power?
The treadle switch itself does not require power to function, but it must be connected to a compatible operator control input.
Is this the same as an in-ground loop detector?
No. A pneumatic treadle is an above-ground hose-style vehicle activator. A loop detector uses wire installed in the pavement and a loop detector module.
Can this be used as a safety device?
Only use it for a safety input when the operator wiring type and installation instructions specifically allow that function. It does not replace required monitored photo eyes or sensing edges.
Why would a treadle kit fail to activate the operator?
Common causes include a damaged hose, loose hose plug, failed air switch, incorrect wiring, or connection to the wrong operator input.
