GTO Bracket, 12" Special Push-to-Open SW4000XL(S)
The R4KPTO is a special push-to-open mounting bracket for selected GTO, Linear PRO and Mighty Mule style swing gate operator installations. In a standard pull-to-open installation, the operator pulls the gate toward the property to open. In a push-to-open layout, the operator pushes the gate away from the property, which changes the bracket location and the arm geometry. This part is used when the original system was set up for push-to-open operation or when an approved conversion is being performed according to the operator installation manual.
Correct bracket selection matters because the SW4000XL/SW4000XLS operator family uses specific mounting distances to keep the arm from binding and to maintain proper leverage through the full gate travel. A bracket that is too short, too long, or mounted in the wrong position can cause poor opening angle, slow movement, blown fuses, nuisance obstruction trips, bent hardware, or premature wear on the gate opener arm. This bracket should be matched to the operator model and the push-to-open instructions, not selected by appearance alone.
This part is commonly purchased when the original push-to-open bracket is missing, bent, heavily rusted, or when a used operator is being reinstalled on a different gate. It is also useful for replacing field-modified brackets that no longer match the factory mounting geometry. Always verify the gate is properly hinged, swings freely, and has the required stops before relying on a replacement bracket to correct an installation problem.
Compatible With
Compatibility should be confirmed by the opener model and installation manual. The R4KPTO is commonly associated with these GTO/Linear PRO push-to-open applications:
- Linear PRO / GTO PRO SW4000XL swing gate opener push-to-open installations
- Linear PRO / GTO PRO SW4000XLS swing gate opener push-to-open installations
- Select SW4200XL and SW4200XLS second-arm installations when used as part of a matching 4000XL/4000XLS dual swing system
- PRO-SW4000XL and PRO-SW4000XLS operator families when the manual calls for the R4KPTO push-to-open bracket
- Not intended as a universal bracket for all Mighty Mule or GTO swing operators; verify the exact arm model, bracket geometry and manual

Technician Note
Do not assume a push-to-open bracket will fix a gate that is binding or sagging. The gate should move smoothly by hand, the hinge side must be solid, and the bracket position must follow the operator manual so the arm does not bottom out or overextend.
Before Ordering Checklist
- Confirm the operator model is SW4000XL, SW4000XLS or a supported related 4200XL/4200XLS arm setup.
- Check whether the existing installation is push-to-open, not standard pull-to-open.
- Compare the old bracket length and mounting style before ordering.
- Review hinge offset, post size and required gate stops in the operator manual.
- Do not mix XL and XLS hardware assumptions without confirming the manual or parts diagram.
Important Ordering Warnings
Some listings refer to SW4000XL, SW4000XLS, 4200XL or 4200XLS together. Those model names are closely related but should still be verified by the operator label and manual before ordering replacement hardware.
Professional Advisory
If the gate is heavy, misaligned, or moving unsafely, have a qualified gate technician inspect the installation before replacing brackets or changing the swing direction.
Product Questions & Answers
What does the R4KPTO bracket do?
The R4KPTO bracket is used on select GTO/Linear swing gate openers when the gate is set up to push open instead of pull open. It changes the mounting geometry so the operator can work in an outward-swinging installation.
Is this bracket for the SW4000XL or SW4000XLS?
It is commonly associated with SW4000XL and SW4000XLS push-to-open applications. Because XL and XLS generations can differ, the safest method is to verify the operator label and parts diagram before ordering.
Can this bracket be used on a dual gate system?
It may be used with select 4200XL or 4200XLS second-arm installations when they are part of the matching SW4000XL/SW4000XLS family and the manual calls for this push-to-open bracket.
Will this bracket work on every Mighty Mule swing opener?
No. This is not a universal Mighty Mule bracket. Smaller arm operators and different model families can use different brackets and mounting dimensions.
Why is bracket geometry important on a push-to-open gate?
The bracket location controls arm travel, leverage and clearance. Incorrect geometry can cause binding, short travel, obstruction trips, blown fuses or damage to the operator arm.
