The LiftMaster K41-0250-000 is an expansion board and terminal block mounting plate replacement kit for LiftMaster INSL24UL and IHSL24UL industrial slide gate operators. This part supports the accessory wiring and expansion board mounting area inside the operator cabinet. It is commonly needed when the original mounting plate is damaged, missing, corroded, or being replaced during a service rebuild. This is a mounting plate service kit and should not be confused with the expansion board itself or the terminal block wiring.
This product page is written for buyers replacing a known LiftMaster part number, not for guessing from appearance alone. Many LiftMaster gate operator parts look similar across generations, so the safest ordering method is to match the part number from the original component, the operator parts diagram, or the model-specific service manual.
Accessory and safety wiring should not be guessed. If the plate replacement requires moving terminal wiring, label each conductor and verify all monitored safety devices before putting the gate back into service.
No. It is the expansion board and terminal block plate or mounting plate. The actual expansion board may be a separate part.
It is commonly listed for LiftMaster INSL24UL and IHSL24UL industrial slide gate operators.
The plate itself does not program the operator, but any wiring moved during service should be checked and tested before the operator is returned to use.
