LiftMaster MS202 #41 Nickel-Plated Drive Chain for Mega Slide Operators
The LiftMaster MS202 drive chain is a replacement #41 nickel-plated chain used in select Mega Slide commercial slide gate operators. The drive chain transfers motor and gearbox movement to the sliding gate system, so chain size, condition, tension, and alignment directly affect how smoothly the gate travels. A stretched, rusted, kinked, or poorly adjusted chain can cause jerky movement, limit drift, excess load on the drive sprocket, or noisy operation. MS202 is typically selected when the operator parts diagram calls for #41 nickel-plated chain rather than stainless steel chain or a different chain pitch. Because slide gate operators operate outdoors and often in harsh environments, the chain should be serviced with the sprockets, idlers, and gate rollers in mind, not treated as an isolated part.

Technician Note
Replace chain only after checking why the old chain failed. Tight spots, worn sprocket teeth, sagging chain, or a dragging slide gate can damage the replacement chain quickly.
Before Ordering Checklist
- Confirm the operator parts diagram calls for MS202 or #41 nickel-plated chain.
- Verify chain length and whether a master link is included.
- Inspect drive sprockets, idlers, and chain guides for wear.
- Check gate rollers, track, and V-groove alignment before returning the gate to service.
- Use the correct #41 connecting link if the chain is supplied without one.
Professional Advisory
Chain replacement on a heavy slide gate can involve stored mechanical force and moving pinch points. A qualified gate technician should handle the repair if the gate is heavy, binding, or unsafe to move manually.
Important Ordering Warnings
- Do not substitute #40, #50, or garage opener chain for #41 operator chain.
- Do not mix worn sprockets with a new chain if the sprocket teeth are hooked or damaged.
- Do not overtighten the chain to compensate for gate drag or bad rollers.

Does the chain include a master link?
Chain listings can vary by supplier. Confirm whether a connecting link is included or order the matching #41 master link if needed.
