Key Features & Benefits
- 4mm pin size — fits 4mm diameter holes in hitch pins, coupling pins and other trailer hardware.
- Spring steel construction — sprung steel wire snaps into the hole and stays in place under vibration, yet is easily removed by hand when needed.
- Sold as a pair — two clips per pack. Keep spares in your trailer toolkit as they can be lost during servicing.
- Universal safety device — used wherever a pin needs to be retained but also needs to be easily removable for servicing.
When to Use These Clips
Use R6223A R clips to retain hitch pins (R1104A), coupling pins and other removable fasteners on your trailer. Always check R clips before each tow — a missing clip means the pin it retains can vibrate out during travel.
