Ulreon Trailer Axle Stop Device — Heavy-Duty Magnetic Tandem Slide Stopper with Rubber Face

Ulreon Trailer Axle Stop Device is a heavy-duty magnetic tandem slide stopper that locks into place to help truckers quickly and accurately position trailer axles.

When snagging the correct axle position matters at weigh stations, loading docks, or on tight roadside shoulders, a reliable stop device saves time and reduces guesswork. The Ulreon magnetic axle stopper combines a powerful magnet, a rubber-faced contact pad, and carbon-steel construction to give drivers a straightforward way to set and hold the trailer tandem without a spotter.

How does this device help me align axles faster?

The Ulreon stopper creates a fixed tactile stop that you can feel and trust as you slide the trailer to the desired position. Instead of inching back and forth and calling for a spotter, you insert the pin and slide until the axle meets the rubber face; the magnet keeps the pad engaged so the setting holds.

• Strong magnet bonded to a resilient rubber face for repeatable stopping.
• Welded carbon-steel handle and pin for one-handed placement and removal.
• Works on both dry vans and refrigerated trailers with standard tandems.

Will it stay in place during driving or when left attached?

The magnetic element is affixed with industrial adhesive beneath the rubber pad, designed to resist vibration and keep the stopper attached during normal use. While intended as an alignment aid rather than a permanent transport latch, the secure bond reduces the risk of accidental separation if a driver forgets to remove it immediately.

• Adhesive-secured magnet prevents loosening from road vibration.
• Durable rubber face absorbs impact and protects mating surfaces.
• Carbon-steel construction reduces bending or deformation under load.

Can I use this with different trailer types and in tough weather?

Yes — Ulreon designed the device for common commercial trailer applications, including semi tractors, dry vans, and refrigerated trailers. Its materials withstand routine exposure to road grime, salt, and temperature swings; the simple mechanical design means fewer failure points in adverse conditions.

• Compatible with standard tandem-slider axles on semi trucks and trailers.
• Robust materials perform reliably in rain, cold, and dusty environments.
• Quick install and removal minimize time spent exposed to the elements.

How do I operate the stop to get consistent results?

Operation is intentionally uncomplicated: insert the lock pin into the slider rail, press the rubber-faced magnet against the axle surface, release the parking brake, and slide until you feel the stop. Retract the pin and move the slider once the setting is complete.

• Insert pin into slider hole, align rubber face to contact point.
• Release parking brake and slide trailer until it contacts the stopper.
• Confirm position visually or with scale, then remove the pin for travel.

Who this is for: The Ulreon Trailer Axle Stop Device is aimed at professional drivers, fleet managers, and owner-operators who need fast, repeatable axle positioning without a second person. It’s particularly useful at weigh stations, during loading/unloading, or when precise axle weight distribution matters. If you want a rugged, low-tech tool that reduces time spent adjusting tandems and increases confidence in axle placement, this magnetic slide stopper is a practical addition to your toolkit.
