The LiftMaster 50102 treadle signal hose is a 10 ft replacement drive-over pneumatic hose for compatible vehicle signal systems. This row is written as a hose-only search path, separate from the exterior air switch and outdoor enclosure references.
What This Part Does
The hose compresses under a vehicle tire and sends an air pulse to a compatible pneumatic switch. The switch then provides the electrical contact signal to the connected control system. A leaking or damaged hose can cause missed activations, intermittent operation, or no signal at all.
Compatible With / Common Applications
Known and commonly referenced uses for the 50102 hose include the following. Confirm length and connection details before ordering.
- Replacement hose for LiftMaster 50102 10 ft treadle signal hose applications.

Technician Notes
- Hose-only replacement is appropriate only when the existing air switch and fittings are still good.
- If the system does not respond after hose replacement, the air switch, fittings, wiring, or control input may also need inspection.
- Avoid sharp bends, pinch points, and tire paths that can crush or cut the hose prematurely.
Before Ordering
- Confirm the existing hose is 10 ft.
- Confirm the fitting style and air switch connection.
- Check whether the air switch is marked 501012 / 50-101-2 if switch replacement is needed.
- Inspect the lane or door approach to make sure the hose is routed correctly.
- Confirm the system uses pneumatic detection, not an inductive loop or photo eye.
Professional Advisory
After replacing a pneumatic hose, test the complete activation circuit several times with the door or gate in view. Do not rely on a treadle hose as a safety reversing device.
Product Questions and Answers
Is this the hose only?
Yes. This row is written as the 10 ft treadle signal hose replacement, separate from the exterior air switch and enclosure hardware.
What symptoms point to a bad treadle hose?
A cracked, leaking, crushed, or cut hose may cause missed activations, intermittent activation, or no response at the connected air switch.
Can this replace any drive-over hose?
No. Match the length, fitting style, hose type, and original parts list. Similar drive-over hoses are not always interchangeable.
What is the difference between 50102 and 501012?
50102 is commonly used for the treadle signal hose, while 501012 / 50-101-2 is commonly used for the exterior SPDT air switch.
Can this be used as a safety edge?
No. This hose is an activation or signal component and should not be used as a replacement for a monitored safety edge or photo eye system.
