HySecurity MX3103, BUMPER REPLACEMENT KIT, SAP
HySecurity MX3103 is a physical stop bumper replacement kit for select HySecurity operator applications. Current listings describe MX3103 as a bumper replacement kit that includes two physical stop bumpers and adjustment screws.
This kit is commonly associated with StrongArmPark DC and WedgeSmart DC applications where the parts diagram confirms MX3103. Because physical stop and bumper hardware can vary by operator family, arm setup, wedge plate setup, production version, and stop location, this kit should be selected only after confirming the operator model and HySecurity parts diagram.
What This Physical Stop Bumper Kit Does
The physical stop bumpers help provide a cushioned stop point where the operator design calls for adjustable physical stop hardware. The bumpers help absorb contact at the stop point and allow the technician to set the bumper position with the included adjustment screws.
Worn, missing, cracked, compressed, misadjusted, or damaged bumpers can contribute to impact noise, harsh stopping, vibration, poor stop contact, hardware wear, or inconsistent arm or wedge stop behavior. Similar symptoms can also be caused by loose mounting hardware, misadjusted stop hardware, damaged brackets, worn pivot parts, gearbox or drive issues, arm impact damage, wedge plate movement issues, or incorrect setup.
Compatible With
Use HySecurity MX3103 only where the operator parts diagram, original bumper kit, or HySecurity documentation confirms this part number.
- Select HySecurity StrongArmPark DC applications where MX3103 is listed as the physical stop bumper replacement kit.
- Select HySecurity WedgeSmart DC applications where MX3103 is listed as the physical stop bumper replacement kit.
- Repairs where the original physical stop bumper kit is marked, listed, or cross-referenced as HySecurity MX3103.
- Applications where the bumper style, adjustment screws, stop location, mounting points, and operator hardware match the HySecurity parts diagram.
- Service repairs where one kit per operator is required and the existing stop bumpers or adjustment screws are worn, damaged, missing, or no longer adjustable.
Important Compatibility Warning
Do not order MX3103 based only on the word "bumper." HySecurity uses different bumpers and stop parts across StrongArmPark DC, WedgeSmart DC, wedge plate assemblies, arm hardware, and other operator families.
MX3103 is commonly described as a physical stop bumper replacement kit with two bumpers and adjustment screws. It should not be confused with WedgeSmart wedge plate bumper kits, breakaway arm hardware, arm bracket kits, drive belts, gearmotors, gearbox parts, or complete operator assemblies.

Technician Note
Before replacing MX3103, inspect the existing bumpers, adjustment screws, stop brackets, mounting points, arm or wedge movement, drive hardware, and any signs of impact or overtravel. If the old bumpers are crushed, torn, unevenly worn, or missing, check whether the operator has been striking the stops too hard or stopping out of adjustment.
Do not use the bumper adjustment to hide a drive, limit, sensor, or mechanical alignment problem. If the operator is hitting the stop aggressively, inspect the controller response, position sensing, drive belt or gearbox where applicable, physical stop alignment, and the full arm or wedge movement path.
Before Ordering, Confirm
- The required part number is MX3103.
- The operator is a StrongArmPark DC, WedgeSmart DC, or other approved application where the parts diagram lists MX3103.
- The repair requires the physical stop bumper kit, not a wedge plate bumper kit, drive belt, gearmotor, gearbox, breakaway bracket, or arm bracket.
- The existing physical stop bumpers and adjustment screws match the MX3103 kit style.
- The stop brackets, mounting points, and surrounding hardware are not bent, cracked, stripped, or missing.
- The operator is not overtraveling because of a drive, sensor, controller, limit, or mechanical setup issue.
- The package includes two physical stop bumpers and adjustment screws, or any missing stop hardware is ordered separately.
- The operator has not been modified with non-standard bumper, stop, arm, or wedge hardware.
Installation and Service Notes
- Disconnect and secure operator power before servicing physical stop hardware.
- Support or secure any moving arm or wedge components before working near the stop area.
- Do not place hands near pinch points, stop points, pulleys, belts, or moving wedge/arm hardware unless the operator is safely powered down.
- Replace damaged bumpers and inspect adjustment screw threads before setup.
- Adjust bumpers only according to the operator service procedure.
- After installation, cycle the operator and check for smooth movement, proper stop contact, abnormal impact, rubbing, noise, or overtravel.
- Verify controller response, position sensing, stop circuits, and all required safety devices before returning the operator to service.
Professional Advisory
Physical stop bumper service should be handled by a qualified gate technician when the repair involves WedgeSmart DC movement, StrongArmPark DC arm movement, drive alignment, sensor faults, impact damage, stop bracket damage, controller setup, or unknown prior modifications. Do not bypass controller protections, position sensors, limit controls, stop circuits, access control safety inputs, photo eyes, safety edges, or any required safety devices to keep the operator running.
Product Questions & Answers

What is included with MX3103?
Current listings describe MX3103 as including two physical stop bumpers and adjustment screws. Package contents should still be verified before ordering.
Is one MX3103 kit enough for one operator?
Current listings commonly state that one kit per operator is needed. Confirm the quantity by the parts diagram and the condition of the installed stop hardware.
Is MX3103 the same as the WedgeSmart wedge plate bumper kit?
No. MX3103 is the physical stop bumper kit. WedgeSmart wedge plate bumper kits, such as MX3699-04 or MX3699-05, are separate related parts and should not be treated as the same item.

Yes. Worn, missing, compressed, or misadjusted bumpers can contribute to noise, vibration, harsh contact, or inconsistent stop behavior. Drive, sensor, controller, and mechanical alignment issues should also be checked.
What should be checked before replacing MX3103?
Check the bumpers, adjustment screws, stop brackets, mounting points, arm or wedge movement, drive hardware, controller response, position sensing, and parts diagram before replacing only the bumper kit.
