The HB100 is the replacement hardware bracket set used to mount compatible Mighty Mule swing gate opener arms to the gate and post structure. These brackets establish the pivot geometry for the actuator. When brackets are bent, missing, installed in the wrong position, or replaced with mismatched hardware, the opener can run out of travel, bind at the end of the stroke, or place extra stress on the arm and gate hinges. Customers typically order HB100 when moving an opener to a new gate, replacing damaged installation hardware, or correcting a worn mount that no longer holds the arm securely.
HB100 should not be treated as the same item as H101P. H101P is the small hardware bag; HB100 is the bracket set. Each opener arm generally needs the correct bracket set, and dual-gate installations may require bracket hardware for each arm depending on what is missing or damaged.
HB100 is commonly associated with these Mighty Mule opener models and related applications when the bracket geometry matches:
| Manufacturer | Mighty Mule / Linear / GTO |
|---|---|
| Product Type | Hardware bracket set |
| Part Number | HB100 |
| Application | Mounting bracket set for compatible swing gate opener arms |
| Compatible Operator Type | Select residential swing gate openers |
| Included Components | Bracket hardware set; contents may vary by supply source |
| Material / Finish | Metal bracket components |
| Notes | Each compatible opener arm generally requires one bracket set |
Common related numbers and references include:
Use HB100 when the physical brackets are the problem. Use H101P when the brackets are still correct and only the small hardware is missing or corroded.
Bracket geometry controls how the actuator loads the gate. Do not install generic or mismatched brackets in place of HB100 where the manufacturer bracket set is required.
Gate opener service can involve stored gate force, moving arms, batteries, and low-voltage control wiring. If the operator is moving unexpectedly, has damaged wiring, or has missing required safety devices, have the system inspected by a qualified gate technician before returning it to service.
No. HB100 is a bracket set. It does not include the actuator arm, motor, control board, transformer, or battery.
HB100 is the bracket set. H101P is the small hardware bag used with compatible mounting parts.
HB100 is listed for several current and older Mighty Mule models including MM371W, MM372W, MM571W, and MM572W when the bracket requirements match.
Each opener arm requires the correct bracket hardware. A dual-gate system may require hardware for both arms if both sides are being serviced.
Yes. Bent or incorrectly positioned brackets can cause binding and overloading, which can shorten actuator life.
