Product Information
The LiftMaster K10-10351 is a replacement capacitor bracket, also commonly referenced as 12A461, for select LiftMaster commercial door operator assemblies. It is used to hold the motor capacitor securely inside the operator housing so the capacitor is not left loose or unsupported during operation. This is the bracket or clamp hardware only; it does not include the capacitor.
Compatibility and Application
This bracket is used with select LiftMaster commercial door operators. Fitment should be verified by the operator's parts diagram because capacitor mounting hardware can vary by operator series and production generation.
Use Notes
- Replacement hardware for holding the capacitor in place.
- Useful when the original clamp is missing, bent, or corroded.
- Not a replacement motor capacitor and not a universal bracket for every operator.

Technician Note
A loose capacitor can rattle, strain its leads, or contact other components inside the operator housing. Replace the bracket if it no longer holds the capacitor firmly, but also inspect the capacitor and wiring for heat or physical damage.
Before Ordering
- Confirm the commercial operator model and parts diagram.
- Compare the old bracket or clamp shape before ordering.
- Do not order this part if the failed component is the capacitor itself.
- Inspect surrounding wiring and capacitor terminals for damage.
Professional Advisory
Capacitors and commercial operator control boxes can involve hazardous stored energy and line voltage. Disconnect power and use a qualified commercial door technician for electrical diagnosis or capacitor replacement.
