Liftmaster K76-34740, LIMIT PASSPOINT KIT
The LiftMaster K76-34740 is the limit passpoint or learn limit assembly kit used on select RSL12V slide gate operators. The limit/passpoint assembly helps the operator establish the gate travel range and recognize the correct open and close movement area. When this assembly is worn, broken, out of position, or electrically failed, the operator may not learn limits correctly or may stop at the wrong location.
Some parts references describe the kit as including the learn limit switch, learn limit nut, limit shaft assembly, sprocket, and wire harness. Kit contents should be checked at time of ordering, especially if the repair requires a complete assembly rather than one individual component.

Technician Note
If the operator will not learn travel, do not assume the limit kit is the only issue. Check gate movement, drive hardware, wiring, batteries, control board, and any stored faults.
Before Ordering
- Confirm RSL12V or RSL12VH model compatibility
- Check whether a full kit or only one limit component is needed
- Compare the existing shaft, sprocket, switch, and harness
- Follow the operator limit-learning procedure after repair
Professional Advisory
Gate travel and limit setup affect safe operation. A gate that overruns, stops unpredictably, or cannot learn limits should be secured and serviced by a qualified gate technician.
Important Ordering Warnings
- Do not broaden this kit to RSL12U or RSL12UL without parts diagram confirmation
- Do not bypass limit or passpoint hardware to keep the gate running
