Tire Thumper with 5th Wheel Release Hook & Container Leverage Bar

One steel tool for your pre-trip and every drop: check tire inflation by sound, pull the 5th wheel release without bending under the trailer, and get the leverage to open stuck container and trailer doors. The OPNBar Tire Thumper is made in the USA and weighs just 3 lb.

3 Tools in 1

• Tire thumper. Strike each tire during your walk-around. A properly inflated tire gives a loud, sharp thud. A low tire gives a dull thud, so you know which one to put a gauge on.
• 5th wheel release hook. Hook the release handle and pull from a standing position. It's designed to cut down on reaching and straining, and helps keep grease, oil and road grime off your clothes.
• Container and trailer door leverage bar. The bar slides over the door latch handle as a handle extender. It gives you extra leverage to open and close shipping container and truck trailer doors, including rusted or iced-over latches.

Ergonomic Design

The OPNBar is designed around the way your body moves when you open a stiff container door. It extends the door latch handle, so you can use a steady pull from your legs and body weight instead of jerking the handle with your wrists and back. Watch the OPNBar ergonomic trucker tool in use:

How to Use

1. Check tires: On your pre-trip inspection, strike each tire's tread with the bar and listen for a sharp, solid thud. Check any tire that sounds dull with a pressure gauge.
2. Release the 5th wheel: Seat the hook on the release handle and pull it out steadily while you stand clear of the tires.
3. Open container doors: Slide the bar over the door latch handle, lift the handle out of its keeper, then rotate it to free the cams. Pull back with your legs, not your back.

FAQ

Does a tire thumper replace a tire pressure gauge?
No. A thumper quickly finds a tire that is flat or badly under-inflated. Confirm the actual pressure with a gauge.

Will it work on rusted or iced-over container doors?
Yes. The leverage bar is built for doors whose latches are stiff from rust or ice.

Do I still need a separate 5th wheel puller?
No. The built-in hook replaces a separate 5th wheel release tool.

Do you offer fleet or wholesale pricing?
Yes. For wholesale orders, contact us or visit opnbar.com. Government buyers can order through GSA contract 47QSEA23D004N.
