Which push-to-open bracket is compatible with my GTO Pro model and gate geometry?
The compatible bracket is determined first by the exact GTO Pro model and XL or XLS generation, then by hinge offset, post or column depth, actuator stroke, gate opening angle, and required clearance. Common matches are 347IH for 2000-series, R4388 for 3000-series, and R4KPTO for 4000-series operators, subject to model verification.
Match the Bracket to the Complete Operator Model
A push-to-open bracket is a model-specific post pivot component. It changes the actuator’s rear pivot location so the arm can extend to open the gate away from the property and retract to close it. It is not the same as the standard post bracket, the gate bracket, the closed-position stop plate, or a generic length of flat steel.
Record the complete operator model before selecting the bracket, including XL or XLS and any secondary-arm designation such as SW2002, SW3200, or SW4200. Housing color or arm size alone is not enough.
| Common GTO Pro Family | Push-to-Open Bracket | Geometry Notes | Compatibility Caution |
|---|---|---|---|
| SW2000XL/XLS and SW2002XL/XLS | 347IH, commonly identified as an 11-inch push-to-open post pivot bracket | Arm is installed fully retracted with the gate closed; verify full extension, clearance, and the gate-bracket position | Also commonly associated with select older GTO Pro families; verify the exact model and parts diagram |
| SW3000XL/XLS and SW3200XL/XLS | R4388 | Match the pivot hole to the hinge setback while keeping the actuator level and clear through the full swing | One bracket is normally required for each actuator in a dual system |
| SW4000XL/XLS and SW4200XL/XLS | R4KPTO, commonly identified as a 12-inch special push-to-open bracket | Heavy-duty arm stroke and post loading make bracket support, bolt size, and structural backing especially important | Do not substitute a 3000-series pivot bracket or a standard 4000-series post component |
Measure the Hinge Offset and Mounting Plane
The correct bracket must place the rear actuator pivot at a workable distance from the hinge centerline. Measure the horizontal distance from the hinge pivot to the face where the post bracket will mount. Also record how far the hinge is set behind the post face, the post or column width, and whether the gate is center-hung, flush-mounted, or attached near the rear corner of a column.
Large masonry columns can restrict pull-to-open clearance. Push-to-open geometry may help, but the bracket still needs structural support. Do not fasten a heavy-duty operator only to veneer, unreinforced hollow block, or deteriorated mortar; use suitable backing or reinforcement.
Model manuals may include A-and-B dimension examples for column installations. Treat those dimensions as model-specific limits, not universal GTO measurements. The 4000XLS documentation, for example, uses a column example where the two referenced offsets must remain within the published total. Recheck the exact diagram for the operator and hinge arrangement before drilling.
Confirm Stroke, Opening Angle, and Two-Inch Clearance
For a push-to-open installation, the gate is normally closed and the actuator fully retracted when the mounting points are established. The arm then extends to open the gate. The bracket hole must provide enough usable stroke to reach the required opening angle without reaching the mechanical end of travel prematurely.
Common GTO Pro XLS instructions require at least two inches of clearance between the gate and operator in both the open and closed positions. Check the actuator body, rear clevis, post pivot bracket, push-pull tube, front mount, and power cable. A bracket position that clears when closed can still bind near 90 or 110 degrees.
Keep the operator level and aligned with a rigid horizontal gate crossmember. Weak pickets or thin sheet can flex under load. Positive stops must establish repeatable travel without forcing the actuator to absorb gate impact.
A Longer Bracket Is Not Automatically Better
Increasing the rear pivot offset changes actuator leverage. Too little offset may prevent outward swing or create contact with the post. Too much offset can reduce mechanical advantage, increase motor current, slow movement, create false obstruction response, or prevent the arm from reaching the desired angle within its stroke.
Do not enlarge holes, stack unrelated brackets, weld an extension onto the factory pivot, or substitute a different model family simply to gain reach. A fabricated arrangement can alter bolt loading, pivot alignment, pinch clearance, and the operator’s listed mounting configuration.
Dual Gates Need Matched Brackets and Mirrored Geometry
A dual push-to-open system normally requires one correct bracket for each actuator. The primary and secondary arms still retain their original roles and cable lengths. Both leaves should use the model-matched bracket and equivalent hinge-to-pivot geometry unless the gate construction requires a documented adjustment.
Check the center gap, gate lock, sequencing, and positive stops. Unequal hinge offsets can make matched arms reach their limits at different times. Do not hide poor geometry with excessive stall force or delay adjustments.
Technician’s Corner
South Florida Wind Load Changes the Required Margin
A solid wood, composite, or sheet-metal gate can place high load on an extended actuator during coastal winds. Correct bracket geometry improves leverage but does not increase the operator’s rated capacity. Confirm gate length, weight, surface area, hinge condition, and wind exposure before relying on a conversion.
Column Depth Is Not the Same as Hinge Offset
A 20-inch column does not automatically require a 20-inch bracket. The meaningful measurements are the hinge centerline, mounting plane, pivot location, actuator body clearance, and desired opening angle. Decorative caps and uneven stone faces can further change the usable mounting plane.
Watch the Cable at Full Extension
The cable must not be pinched or stretched at full travel. Salt air, vibration, and repeated flexing can damage insulation near the strain relief.
Changing Direction Changes the Entrapment Zones
An outward-swinging gate creates new opening-direction hazards near fences, walls, parked vehicles, posts, and landscaping. Reevaluate photo eyes, sensing edges, warning signs, screening, and emergency access. The gate must not swing into a roadway, sidewalk, bike path, or other public-access area.
Before You Match the Push-to-Open Hardware
- Record the complete operator and actuator model, including XL or XLS and primary or secondary designation.
- Measure hinge centerline to mounting plane, hinge setback, post or column depth, and required opening angle.
- Confirm the bracket part number from the exact operator manual or parts diagram.
- Verify two inches of operator-to-gate clearance in both open and closed positions.
- Check actuator stroke, retracted length, level mounting, cable clearance, and gate crossmember strength.
- Inspect posts, columns, hinges, stops, welds, and structural backing.
- Confirm the board’s push-to-open setting and relearn limits after the mechanical installation is correct.
- Review opening- and closing-direction entrapment protection for the new swing path.

The correct bracket is the model-specific pivot that allows full outward travel, safe clearance, efficient leverage, and secure structural mounting. Before selecting replacement hardware, verify the complete model number, bracket part number, XL or XLS generation, actuator stroke, hinge offset, post geometry, opening angle, board revision, and safety-device requirements.
