Liftmaster 10-18461, SIDE COVER
The LiftMaster 10-18461 is a side cover used on the SW470 and SW490 swing gate operator family. Side covers protect the operator's internal mechanical and electrical areas from direct exposure and help keep the enclosure properly closed after service. A broken or missing cover can allow rain, debris, insects, and yard maintenance damage to reach parts that were meant to stay protected. In the field, this part is normally ordered after impact damage, age-related cracking, missing hardware, or cabinet service where the original panel no longer fits correctly. Because SW470 and SW490 operators have existed in different configurations, the installed cabinet style and parts diagram should be checked before ordering. This part is also referenced by older numbers 10-2105-T and G102105T.

Technician Note
Before replacing this part, inspect the surrounding hardware, mounting points, wiring where applicable, and any related drive or sensing components. A failed surrounding part can make a good replacement part appear defective after installation.
Before Ordering
- Confirm the operator model and serial or generation when available.
- Compare the original part number with the number listed on this product page.
- Review the operator parts diagram for the exact service part location.
- Check dimensions, mounting style, connector style, chain size, or finish where applicable.
- Do not substitute similar-looking parts unless the parts diagram confirms the match.
Professional Advisory
Gate operators can move heavy gates and may include high-voltage circuits, stored spring force, pinch points, and monitored safety devices. Mechanical repairs should be completed with the operator secured and power disconnected where required. Electrical testing, high-voltage work, and safety-device issues should be handled by a qualified gate technician.
