GTO Silver bracket set w/ captured gate bracket
The captured gate bracket design helps keep the arm attachment more secure than an open-style bracket arrangement. In practical service work, this set is often ordered after a gate has been hit, brackets have elongated holes, the original hardware is missing, or a customer is reinstalling a used operator on a new gate. Replacing worn brackets can reduce looseness and help restore proper opener geometry.

Technician Note
HB100 and H101P are different parts. HB100 is the major bracket set. H101P is a smaller hardware bag. A loose gate arm may need one, the other, or both depending on what is missing or damaged.
Before Ordering Checklist
- Confirm the opener model and arm generation
- Inspect whether the major brackets are bent or worn
- Check whether you also need the small hardware bag, pins, or clips
- For dual swing gates, confirm the quantity needed per arm
- Compare bracket geometry to the original before installing
Professional Advisory
Bracket replacement affects gate movement and leverage. If the gate is sagging, the post is loose, or the opener has been damaged, have the full installation checked instead of only replacing brackets.
Important Ordering Warnings
- HB100 is not a universal bracket kit for every GTO, Linear, or Mighty Mule opener
- Current Mighty Mule compatibility may differ from older GTO PRO compatibility lists
- Do not mix bracket parts from different operators without verifying geometry
- Bent brackets often indicate the gate or operator should be inspected for a larger issue
Product Questions & Answers
Is HB100 the same as H101P?
No. HB100 is a major bracket set. H101P is a hardware bag with smaller installation hardware.
How many HB100 bracket sets are needed?
One HB100 set is typically used per swing gate opener arm. A dual swing gate may need two sets if both arms require bracket replacement.
Which Mighty Mule openers are commonly associated with HB100?
Listings commonly reference MM350, MM500, MM502, FM350, FM500, and several newer MM series models, but always verify the model and bracket diagram.
What does a captured gate bracket help with?
A captured gate bracket helps secure the arm connection at the gate end and can reduce the chance of unwanted disengagement when installed correctly.
Should I replace brackets after a gate impact?
Yes, inspect and replace bent or elongated brackets. Also check the opener arm, gate post, hinge side, and gate alignment before returning the system to service.
