LiftMaster K76-37325 Limit Rack / Limit Assembly Kit — CSW200U-Series

The LiftMaster K76-37325 is the limit-rack assembly identified in documented CSW200U and corresponding CSW200UL swing-gate operator repair information. It belongs to the mechanism that establishes travel stopping points and must match the installed operator generation. This reference is distinct from older Q165 / K75-50189 arrangements and from the SL3000 limit kit, even when those parts appear in a shared family manual. Select the assembly after checking the switches, mechanical actuation and wiring, then complete the required limit adjustment and safety tests after installation.

Compatibility — Models, Versions and Exclusions

Confirm the Limit Mechanism and Cause of the Fault

A gate that stops inconsistently may have a worn or loose mechanical component, switch fault, connection problem or drive issue. Have the technician inspect the full limit arrangement before deciding whether the complete assembly or an individual part is required. A new assembly does not correct a damaged drive connection or a gate that binds before reaching its intended endpoint.

The same manual can cover more than one operator, with separate parts drawings for each. Identify the CSW200 limit arrangement and record the complete model before choosing the kit. Do not carry a limit reference across to an SL3000 merely because the manual cover lists both families. After replacement, adjust and test both travel endpoints under the actual operator’s procedure, keeping the gate area clear throughout supervised testing.

Specifications and Product Identification

Before Ordering

• Record the complete CSW200 model and production generation.
• Match the installed limit arrangement to K76-37325.
• Inspect mechanical actuation, switches, wiring and retention.
• Confirm current kit contents and the required limit-setting procedure.

Package Contents and Separate Requirements

This offer identifies the K76-37325 limit-rack service assembly. Confirm the supplied switches, brackets, cams and mounting pieces against the current kit inventory. A main control board, motor, complete gearbox, gate arm and operator are not promised as included. The surrounding repair drawing can show individually available parts as well as an assembly, so determine the intended repair scope before ordering.

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 protection option only where the exact operator and control revision approve it; not a universal legacy retrofit.
• LMWEKITU monitored wireless edge kit — a separate edge communication system for approved controls and resistive edges; not a replacement for this mechanical or electrical service part.

Frequently Asked Questions

Is this the SL3000 limit kit?

No. The documented SL3000 arrangement uses a separate reference.

Can it replace every older CSW limit assembly?

No. Match the actual generation and service number.

Does a new assembly eliminate limit adjustment?

No. Follow the prescribed setup and test both travel endpoints.

Will it fix a gate that binds mechanically?

No. Gate or drive resistance requires separate correction.
