NICE / APOLLO MX4005, Arm Assembly, Universal, Next Gen
The NICE HySecurity MX4005 is a universal Next Gen swing arm assembly used on compatible HySecurity/Nice swing gate operators. In practical service work, this part is ordered when the original arm assembly is bent, worn at the pivot, damaged from impact, missing hardware, or being updated from an older compatible arm reference. It is a structural motion component, so fitment is based on the complete operator arm design and mounting geometry, not simply on the gate being a swing gate.
This part should not be confused with Apollo linear actuator arms such as 416, 816, 912L, Titan, or Vanguard 3500 style assemblies. Those are different operator families. The MX4005 belongs to the SwingSmart / HySecurity style arm assembly group and should be matched by part number, diagram location, and the installed operator chassis.
Compatible With
Commonly associated with HySecurity/Nice SwingSmart DC and SwingSmart-style swing operator arm assemblies where the parts diagram identifies MX4005. Public references also show MX002011 as an older articulating SwingSmart DC arm assembly replaced by or related to MX4005. Verify by model, serial range, arm geometry, and diagram before ordering.

Technician Note
If an arm assembly failed from impact or binding, inspect the gate stops, hinges, mounting post, operator base, and obstruction settings before putting the replacement into service.
Before Ordering
- Confirm the installed operator family and serial range.
- Compare the existing arm shape and pivot points to MX4005 references.
- Do not use this as a substitute for linear actuator arms.
- Check related pivot hardware and brackets for wear.
- Confirm the gate moves freely through the full swing arc.
Professional Advisory
After replacement, the gate should be tested for proper limits, speed, obstruction response, and safe travel. Structural gate problems should be corrected before returning the operator to service.
Product Questions and Answers
What is the MX4005 arm assembly used for?
MX4005 is a universal Next Gen arm assembly used as a replacement crank or articulating arm assembly on compatible HySecurity/Nice swing operators.
Is MX4005 related to MX002011?
Yes. Public parts references list MX002011 as an articulating SwingSmart DC arm assembly with new part number MX4005.
Is this an Apollo 816 or 912L actuator arm?
No. MX4005 is not a linear actuator arm like Apollo 816 or Titan 912L. It is for compatible SwingSmart style arm assemblies.
Can I use it on any swing gate opener?
No. It must be matched to the compatible HySecurity/Nice operator and arm assembly design, not just the fact that it is a swing gate.
What should be checked before replacing the arm?
Check arm length, mounting points, hinge geometry, hardware condition, and the operator parts diagram before ordering.
