GTO SW4200XLS Secondary Swing Gate Opener
The GTO SW4200XLS Secondary Swing Gate Opener is the secondary actuator arm used to convert or service a compatible 4000XLS-family swing gate system for dual vehicular gate operation. In a dual system, the primary operator and control box manage the timing, accessory inputs, safety response, charging, and gate sequencing. The secondary arm is wired back to that master control system and moves the second gate leaf in the proper order.
This is a common ordering point where mistakes happen. A second arm is not the same as a complete opener kit, and it should not be ordered as a stand-alone replacement for a single swing gate unless the existing system calls for that exact part. The arm must match the master control board generation, operator series, cable layout, and gate geometry. The 4200XLS second arm is commonly paired with the 4000XLS primary operator for gates rated up to 20 ft. or 1000 lb. per leaf when properly installed.
Dual swing gates need more attention than a single gate because both leaves must close against the proper stops, stay aligned, and maintain the correct opening and closing sequence. If an automatic gate lock is being used, the lock leaf, receiver leaf, positive stops, and control-board sequencing all have to work together. Before replacing or adding this arm, check the existing control box label and confirm whether the system is an older XL generation or the newer XLS generation.
Compatible With
Select dual swing gate systems using a compatible PRO-SW4000XLS primary/master operator; Linear Pro Access, GTO PRO, and Mighty Mule Pro 4000XLS-family installations; dual vehicular swing gates up to 20 ft. or 1000 lb. per leaf when the gate and mounting layout are within specification; pull-to-open and properly configured push-to-open dual layouts; transformer or compatible solar charged 12 VDC systems. Verify the master control box, cable routing, gate sequencing, stop positions, and whether the existing equipment is XL or XLS generation before ordering.

Technician Note
For dual gates, verify both gate leaves independently. A good primary arm will not correct a dragging secondary leaf, weak hinge post, missing positive stop, or incorrect gate lock alignment. If the system was built from mixed XL and XLS parts, identify the control board before ordering a replacement arm.
Before Ordering Checklist
- Confirm the existing primary operator is a compatible 4000XLS-family master system.
- Verify whether the current system is XL or XLS generation.
- Measure each gate leaf and confirm weight, hinge condition, and travel clearance.
- Check the required second-arm cable route and length.
- Review gate sequencing if an automatic gate lock is installed.
- Confirm stops and safety devices are in place and working.
Professional Advisory
Do not wire a second arm into an unknown control board or bypass monitored safety functions. Dual gate troubleshooting can involve moving equipment, battery power, and control-board settings. Use a qualified gate technician when the gate is heavy, out of alignment, or behaving unpredictably.
Product Questions
Can the PRO-SW4200XLS run a gate by itself?
No. The PRO-SW4200XLS is a secondary operator arm for a dual swing gate layout and must be used with the correct primary/master 4000XLS control system.
Which primary opener does this second arm match?
It is commonly matched with the PRO-SW4000XLS primary swing gate opener for a 4000XLS dual swing gate installation.
Does the second arm include the master control board?
A second-arm kit is normally used as an add-on arm and should not be treated as a complete single-gate opener kit. Review the kit contents before ordering.
Why does dual gate sequencing matter?
In a dual gate system, one leaf opens first and closes last depending on the layout, stops, and gate lock position. Incorrect sequencing can cause poor closing or lock alignment problems.
Can this be used with older 4200XL equipment?
Do not assume XLS and XL parts interchange. Match the existing arm, control board, and parts diagram before mixing generations.
