Liftmaster K75-50893, SAFETY INTERLINK KIT
The LiftMaster K75-50893 is a service replacement safety interlink kit used in the manual crank area of select Elite and LiftMaster SL3000 slide gate operators. On these older commercial slide gate systems, the crank access and interlock hardware are part of the operator design that helps prevent unsafe operation when the manual release or crank function is being serviced. A damaged or missing interlink kit can leave the crank area incomplete, make service access difficult, or create confusion when diagnosing manual operation issues.
This is a model-specific mechanical and safety-related service kit. It should be ordered by part number from the SL3000 parts breakdown and installed only where the operator documentation calls for K75-50893 or a safety/interlock assembly in that position.

- Check the SL3000 parts diagram for K75-50893
- Inspect the existing crank access/interlock hardware for missing pieces
- Do not order this to replace monitored photo eyes, edge sensors, or other external safety devices
Professional Advisory
Gate operators with damaged interlock hardware, unsafe manual release behavior, or altered safety wiring should be serviced by a qualified gate technician before being placed back into operation.
Important Ordering Warnings
- Do not bypass an interlock or safety circuit to keep an operator running
- Not a universal SL-series kit; verify by parts diagram
