Nice Apollo 3398 Threaded Rubber Gate Stop Bumper
The Nice Apollo 3398 is a threaded rubber gate stop bumper used as a physical cushion where a gate contacts a stop point. Even on an automatic gate system, the gate should have proper mechanical stops and should not slam metal-to-metal against posts, brackets, or operator hardware. A rubber bumper helps absorb contact, reduce noise, and protect the gate finish and hardware from repeated impact. This part is commonly used on swing or slide gate installations where a simple threaded bumper is needed at the open or closed stop point. It is a hardware bumper only. It is not an electronic safety device, monitored edge, reversing sensor, or replacement for required entrapment protection. Fitment depends on thread size, bumper diameter, mounting bracket, gate clearance, and the actual stop design. Replace a torn, missing, hardened, or flattened bumper before gate impact damages nearby hardware.
Compatible With
- Gate stop points using a compatible 3/8-16 threaded bumper mount.
- Residential and commercial swing gate stop brackets where a rubber contact bumper is needed.
- Slide gate or general gate hardware stops where the bumper size and thread fit the bracket.
- Apollo/Nice gate installations using part number 3398 for the stop bumper.
- May be used on non-Apollo gate hardware if the thread, clearance, and stop design match.
This is a general gate stop bumper, not an operator-specific electrical part. Verify physical dimensions before ordering.

Technician Note
If the bumper is being destroyed quickly, check gate alignment, limit settings, stop placement, and operator force. The bumper should cushion contact, not absorb a hard slam every cycle.
Before Ordering
- Confirm the bumper thread is 3/8-16.
- Measure clearance at the stop location.
- Check whether the bracket accepts a threaded bumper.
- Inspect the gate for excessive force or misalignment.
- Do not use this as a monitored safety edge.
Important Ordering Warnings
This bumper is a mechanical cushion only. It does not sense obstruction and does not replace required gate safety devices.
Professional Advisory
Gate operator parts should be matched by the operator model, part number, voltage, connector style, and installed accessory layout. For electrical diagnosis, safety-device issues, or unsafe gate movement, use a qualified gate technician. Do not bypass required safety devices to make an operator run.
