LiftMaster K41-0247-000 Limit System for INSL24UL and IHSL24UL
The LiftMaster K41-0247-000 is the limit system service kit for INSL24UL and IHSL24UL industrial slide gate operators. The limit system is a key part of gate travel control because it helps the operator understand where the gate should stop in the open and close directions. A worn, damaged, misread, or incorrectly adjusted limit system can cause overtravel, short travel, nuisance faults, inconsistent stopping points, or a gate that will not complete a cycle. This part should be selected by the operator parts diagram and the actual limit-system layout in the cabinet. It is not the same as a chain, output sprocket, board, or motor replacement, even though travel problems can involve more than one of those parts. After replacement, the operator travel and obstruction settings should be set according to the LiftMaster instructions and tested with all required monitored safety devices connected.

Technician Note
A travel problem is not always a limit system failure. Check chain tension, gate drag, encoder/limit references, board faults, and obstruction settings before ordering. If the original part failed after a surge, water intrusion, gate impact, or mechanical binding condition, correct that problem before installing the replacement part.
Before Ordering
- Confirm the LiftMaster operator model and any MC or package-code reference on the data label.
- Compare the installed part number and connector style against the current parts diagram.
- Inspect related drive, wiring, battery, control-board, and safety-device components before replacing parts.
- Do not use similar-looking INSL24UL and IHSL24UL parts interchangeably unless the parts diagram confirms it.
- Use a qualified gate technician for high-voltage, battery, motor, drive-board, or moving-gate service.
Professional Advisory
Industrial slide gate operators are powerful pieces of moving equipment. After any motor, board, limit, harness, alarm, or gear reducer repair, the gate must be tested through a complete open and close cycle with all required monitored safety devices connected and operating. Do not bypass photo eyes, safety edges, interlocks, alarms, or other entrapment protection devices to force the operator to run.
Important Ordering Warnings
- INSL24UL and IHSL24UL parts can look similar but may not interchange.
- Model suffixes, package codes, and parts-diagram revisions can affect the correct service part.
- Electrical faults, water damage, or gate binding can damage replacement parts if left unresolved.
- Compatibility is based on supported model families and should be verified against the installed operator.
Product Questions & Answers
What does the K41-0247-000 limit system do?
K41-0247-000 helps the supported INSL24UL and IHSL24UL operators control and recognize gate travel limits in the open and close directions.
What symptoms may indicate a limit system problem?
Symptoms can include overtravel, short travel, inconsistent stopping, travel faults, or a gate that will not complete a full open or close cycle.
Does the gate need to be reset after replacing the limit system?
Yes. Travel and operator setup should be checked and set according to the LiftMaster instructions after limit-system service.
Can a chain or gate problem look like a bad limit system?
Yes. Chain tension, worn sprockets, gate drag, damaged rollers, and obstruction settings can create travel symptoms, so the mechanical system should be checked too.
Does this part fit both INSL24UL and IHSL24UL?
Yes, this part is listed for both INSL24UL and IHSL24UL model families where the parts diagram calls for K41-0247-000.
