Mighty Mule 347IH 11 Inch Post Pivot Push-To-Open Bracket for FM500, FM502, FM600 and Related Operators
The 347IH is the 11 inch post pivot bracket used for push-to-open gate opener geometry on compatible Mighty Mule, GTO, and Linear swing gate operators. In a normal pull-to-open installation, the arm pulls the gate inward to open. In a push-to-open installation, the arm pushes the gate outward or away from the property, which changes the pivot point and bracket requirements. This bracket helps place the opener arm at the correct angle so the actuator can move through its travel without binding or overloading. Customers usually need this part when the gate layout does not allow a standard pull-to-open setup or when an existing push-to-open bracket is bent, missing, or corroded.
Because push-to-open geometry is more sensitive than many standard pull-to-open installations, the bracket must be matched to the opener model and the installation manual. Gate stops, hinge condition, and post offset all matter. This bracket should not be used to force a standard installation into a different geometry without checking the manual.

- Mighty Mule FM500 and FM502 push-to-open installations
- Mighty Mule FM600 push-to-open installations
- Select GTO / Linear / Mighty Mule swing gate opener installations requiring an 11 inch post pivot bracket
- Related push-to-open bracket references for older FM and PRO swing operator layouts
- Not a replacement for standard HB100 pull-to-open bracket hardware unless the push-to-open layout is confirmed

Technician Note
A push-to-open bracket should be selected by gate geometry, not just by model number. The wrong post pivot location can make the arm hit its limit early or pull the gate out of alignment.
Before Ordering
- Confirm the gate is truly a push-to-open installation.
- Review the operator manual for push-to-open bracket placement.
- Measure post offset and gate hinge position.
- Inspect gate stops and make sure the gate cannot overtravel.
- Do not substitute this for standard pull-to-open bracket parts unless the layout requires it.
Important Ordering Warnings
Push-to-open bracket errors can create unsafe gate movement or operator overloading. If the geometry is unclear, have a qualified gate technician lay out the bracket position before installing the operator.
Professional Advisory
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.
Product-Specific Q&A
What is the 347IH bracket used for?
It is used as an 11 inch post pivot bracket for select push-to-open swing gate opener installations.
Is 347IH needed on every FM502 or FM600 installation?
No. It is normally used when the gate must push open. Standard pull-to-open installations use different bracket geometry.
Can this replace HB100?
Not directly. HB100 is a standard hardware bracket set, while 347IH is tied to push-to-open post pivot geometry.
What happens if the wrong push-to-open bracket is used?
The opener arm may bind, run out of travel, strain the gate hinges, or fail to reach proper open and closed positions.
Should gate stops be used with push-to-open systems?
Yes. Proper gate stops and correct bracket geometry help prevent overtravel and reduce stress on the operator.
