Mighty Mule FM500 Parts - 347IH Bracket / 11 inch Post Pivot - Push-To-Open
The 347IH is a service bracket for Mighty Mule / GTO swing gate opener installations where the operator arm needs the correct 11 inch post pivot spacing for a push-to-open arrangement. The bracket does not control the gate electronically, but it has a major effect on how the actuator travels. If the pivot point is too short, too long, or mounted at the wrong angle, the arm can bind, bottom out, overtravel, or push against the gate stop instead of moving smoothly. This is why bracket selection should be handled like a fitment part, not just a piece of hardware. It is commonly searched for FM500 and FM502 replacement parts, but the correct bracket depends on the operator, gate swing direction, hinge offset, post position and whether the installation is push-to-open or pull-to-open.
Compatible With
- Mighty Mule FM500 and FM502 swing gate operators when the parts diagram calls for 347IH or an 11 inch post pivot push-to-open bracket.
- Select Mighty Mule FM350/FM352 and GTO/Linear swing gate systems may use related push-to-open bracket hardware depending on installation geometry.
- Commonly associated with GTO / Mighty Mule push-to-open conversion and replacement bracket layouts.
- Verify by original bracket length, hole spacing, installation manual and the actual gate/post geometry before ordering.

Technician Note
Before replacing this bracket, compare the existing bracket length and mounting hole layout. A bracket that looks close can still change the actuator geometry enough to cause binding or limit problems.
Before Ordering Checklist
- Confirm the opener model and whether the installation is push-to-open or pull-to-open.
- Measure the existing bracket length and compare the mounting hole layout.
- Check hinge offset and post position against the installation manual.
- Inspect the gate for sagging or hinge bind before replacing only the bracket.
- Do not modify safety stops or gate stops to force a mismatched bracket to work.
Important Ordering Warnings
- Push-to-open and pull-to-open hardware should not be mixed without checking the manual.
- Wrong bracket geometry can damage the arm, control board, gate hinges or mounting post.
Professional Advisory
Bracket changes can affect gate force and travel. If the gate binds, drags, or does not have proper stops, correct the mechanical issue before operating the automatic opener.
Product Questions & Answers
What is the 347IH bracket used for?
The 347IH is an 11 inch post pivot bracket used in push-to-open bracket geometry on select Mighty Mule and GTO swing gate opener installations.
Is 347IH the same as the standard pull-to-open bracket hardware?
No. Push-to-open installations use different bracket geometry. Do not substitute standard brackets without checking the installation manual.
Can this bracket be used on an FM500 opener?
It is commonly listed with FM500, FM502 and similar Mighty Mule swing gate operator parts, but the installation type and arm geometry must match.
Why does bracket length matter on a swing gate opener?
Bracket length affects leverage, stroke travel, gate stop position and motor load. Wrong geometry can cause binding, short travel or control board current faults.
Should this bracket be welded or bolted?
Follow the operator installation manual and the gate/post construction. If the post or hinge layout is unusual, a gate technician should verify the bracket location before mounting.
