HySecurity MX4238, Arm, Rod End, Swivel
The HySecurity MX4238 swivel rod end is a service component for the newer universal arm assembly used on select SwingSmart operators. A rod end is a pivoting connection point that lets the arm assembly move through its swing arc without binding. If the joint becomes loose or damaged, the gate can develop inconsistent travel, added noise, uneven loading, or stress at the mounting bracket and operator output. This part is most commonly tied to MX4005 universal arm assembly service and to SwingSmart CNX and SwingSmart DC units after the October 2018 arm-generation change. Always confirm the arm style, operator model, hand configuration, and parts diagram before ordering.

This is an OEM-style HySecurity replacement part. Similar-looking HySecurity parts may differ by operator family, generation, voltage, harness length, handedness, or mechanical position. Use the original part number and the operator parts diagram as the final fitment check.
Before Ordering Checklist
- Confirm the HySecurity model and operator family.
- Match the full part number, including any suffix.
- Compare the original part location, connector, hardware, and mounting style.
- Check surrounding parts for wear or damage before replacing only one component.
- For hydraulic, high-load mechanical, or electrical repairs, use a qualified gate technician.
Professional Advisory
Gate and barrier equipment can move with significant force and may contain stored mechanical energy, hydraulic pressure, or live electrical circuits. Do not bypass safety devices, guards, sensors, or interlocks. If the system has uncontrolled movement, missing guards, damaged wiring, hydraulic leakage, or uncertain compatibility, stop operation and have the equipment inspected by a qualified technician.
Product Questions and Answers
What assembly is MX4238 commonly used with?
MX4238 is commonly associated with the MX4005 universal arm assembly used on select SwingSmart CNX and post-October 2018 SwingSmart DC operators.
What does a swivel rod end do?
It provides a pivoting connection point so the swing gate arm assembly can move through its travel without binding.
Will MX4238 fit older SwingSmart DC arms?
Not always. The operator generation and arm assembly must be checked, especially for units built before the October 2018 arm update.
What symptoms can point to a worn rod end?
Loose arm movement, noise, uneven gate travel, binding, or visible joint wear can point to a worn rod end or related arm hardware.
Is MX4238 the complete universal arm assembly?
No. MX4238 is a rod end component. Complete arm assemblies or service kits use separate part numbers.
