The LiftMaster 19-3025 is a #50 x 471 link replacement chain supplied without a master link for select LiftMaster commercial slide gate operators and perimeter access systems. It is commonly referenced as a #50 nickel-plated 25 ft chain in INSL24UL and IHSL24UL industrial slide gate operator parts information. This chain is used in heavier slide gate drive applications where a larger #50 chain is required. It should not be substituted for smaller #40 or #41 chain kits, and a compatible #50 master link should be ordered separately when needed.
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.
