LiftMaster 19-41750 #41 x 750 Gate Operator Chain
The LiftMaster 19-41750 is a #41 x 750 replacement drive chain for select gate operator applications. It is commonly described as a 30 ft #41 roller chain and is supplied without a master link.
This type of chain is used in sliding gate and other chain-drive gate operator systems where the chain transmits motor and gearbox movement to the gate or drive assembly. If the chain is stretched, rusted, stiff, or damaged, the operator may chatter, jump teeth, stop short, or place extra load on the motor. Matching the correct chain size is important because #41 chain is not interchangeable with #40 or #50 chain even when the parts look similar at a glance.

Technician Note
If the old chain shows rust, stiff sections, or uneven wear, check the operator sprockets and gate rollers. Chain wear is often a symptom of poor alignment or gate drag.
Before Ordering Checklist
- Confirm the required chain is #41 pitch.
- Verify the operator calls for 19-41750 or #41 x 750 chain.
- Order compatible #41 master links if needed.
- Inspect drive and idler sprockets for hooked teeth.
- Check gate movement manually before setting final chain tension.
Professional Advisory
Gate chain replacement should be performed with the operator powered down and the gate secured. Heavy slide gates can move unexpectedly if not properly controlled.
