LiftMaster 50102 Treadle Signal Hose for Outdoor Applications
The LiftMaster 50102 is a 10 ft treadle signal hose used in pneumatic vehicle signal systems. This listing is written around outdoor enclosure style applications where the hose feeds an air switch in a compatible commercial door, gate, parking, service station, or access-control setup.
What This Part Does
The hose acts as the drive-over sensing tube. When a vehicle tire compresses the hose, the air pulse travels to the air switch, and the switch sends a contact signal to the connected control equipment. The hose by itself does not process the signal and does not replace the air switch or control board.
Compatible With / Common Applications
Known and commonly referenced uses for 50102 include the following. Confirm hose length, enclosure, fittings, and air switch before ordering.
- 10 ft pneumatic treadle hose applications for compatible LiftMaster air switch systems.
- Outdoor enclosure / NEMA 4/12 style pneumatic signal setups when the original parts list calls for 50102.
- Vehicle drive-over signal systems used at service stations, commercial doors, car washes, parking controls, apartment entries, and gate control applications.
- Replacement hose for pneumatic treadle systems where the original hose is 10 ft and marked or specified as 50102.
- Indoor or outdoor use when the surrounding enclosure, fittings, and air switch are suitable for the installation.

Technician Notes
- Do not confuse 50102 treadle hose with 501012 exterior air switch.
- A 10 ft hose may not be correct for every lane width or mounting layout.
- Outdoor installations should be protected from abrasion, water entry, crushing damage, and improper vehicle approach angle.
Before Ordering
- Confirm the existing hose length is 10 ft or that 10 ft is correct for the installation.
- Confirm the system uses pneumatic hose and an air switch, not an inductive loop or photo eye.
- Inspect the fittings and air switch before replacing only the hose.
- Confirm whether you need the hose-only item or a complete enclosure/switch assembly.
- Do not route hose where it can be cut, pinched, or damaged by traffic.
Professional Advisory
If this hose is part of a commercial door or gate activation circuit, the full control system should be tested after replacement. Do not use a treadle hose as a substitute for required safety photo eyes, monitored edges, or UL 325 safety devices.
Product Questions and Answers
What is LiftMaster 50102 used for?
LiftMaster 50102 is a 10 ft treadle signal hose used in pneumatic drive-over vehicle signal systems.
Is 50102 the exterior air switch?
No. 50102 is the treadle hose reference. The exterior SPDT air switch is commonly referenced as 501012 or 50-101-2.
Can this hose be used outdoors?
It is commonly referenced with outdoor enclosure applications, but the enclosure, fittings, routing, and air switch must be suitable for outdoor use.
Does this hose open a gate by itself?
No. The hose creates an air pulse for a compatible air switch. The connected control equipment must be wired and configured properly.
Is this a safety device?
No. A treadle signal hose is an activation or signal component and should not replace required monitored safety devices.
