LiftMaster Q024 / K75-50097 Legacy Slide-Gate Limit Switch Kit

The LiftMaster Q024 identifies manufacturer limit-switch kit K75-50097 for the applicable legacy slide-gate travel mechanism. The manufacturer service-parts guide shows a broader assembly than the individual Q032 limit nut, with associated shaft, sprocket and bearing components identified in its breakdown. Match the complete kit to the installed operator generation before purchase. It is not the newer K76-37306 assembly, an electronic position encoder or a universal limit system for every SL3000-branded operator.

Compatibility — Models, Versions and Exclusions

Choose the Correct Limit Assembly for the Operator Generation

The SL3000 name spans different hardware generations. The legacy Omni service breakdown and later SL3000U drawings identify different limit assemblies, so the complete model and installed mechanism must be checked together. Photograph the existing shaft, switches and drive connection before ordering. A similar enclosure does not establish that its internal limit system matches this kit.

Decide whether the problem requires the complete assembly or an individual service component. A damaged shaft, worn nut, loose bearing or electrical switch fault can affect the stopping position. Have the technician diagnose the whole mechanism and its drive before choosing the package. After repair, follow the model-specific limit adjustment and test both travel endpoints under supervised conditions.

Specifications and Product Identification

Before Ordering

• Record the exact operator model and controller generation.
• Match K75-50097 / Q024 to the installed limit system.
• Inspect the mechanism, electrical switches and related drive parts.
• Confirm the current kit inventory and required setup procedure.

Package Contents and Separate Requirements

This offer identifies the Q024 limit-switch kit. The manufacturer service breakdown identifies the limit shaft, nut, sprocket, bearing kit and collar within the assembly structure; confirm the actual carton and any separately supplied electrical or mounting parts before ordering. Do not assume every component in a surrounding operator diagram is included, or that the individual Q032 offer provides this complete repair scope.

Safety Warnings — Read Before Installation or Service

• WARNING: A faulty or incorrectly adjusted limit assembly can allow dangerous gate travel. Use a qualified gate-systems technician.
• Isolate all applicable power and secure the gate before removing the limit mechanism.
• Do not bypass limits or return a gate with unreliable stopping to normal service. Keep people clear during supervised adjustment.
• Verify both endpoints, reversal and every required entrapment-protection device before normal operation resumes.

Related Products and Important Differences

• LMRRUL monitored photo eye — a separate safety accessory only where the installed control system approves it; not a replacement limit switch.
• LMWEKITU monitored wireless edge kit — a separate protection-system component with its own compatibility requirements; it does not establish travel endpoints.

Frequently Asked Questions

Is Q024 just the limit adjustment nut?

No. Q032 / K75-50101 identifies the individual nut. Q024 is the broader K75-50097 kit reference.

Will it replace K76-37306?

No interchangeability is established. The references belong to different documented limit arrangements.

Can I select it from the SL3000 name alone?

No. Confirm the operator generation and installed assembly using the applicable parts diagram.

Does a replacement assembly remove the need to set limits?

No. The technician must complete the prescribed adjustment and operating tests after installation.
