Yoolon Magnetic Tandem Slide Stopper — Trailer Axle Stop Device, Black Rubber Face with Built-In Magnet for Faster Tandem Adjustme

The Yoolon Magnetic Tandem Slide Stopper is a heavy-duty trailer axle stop device that locks onto the tandem slider hole with a built-in magnet so you can set axle position quickly and securely.

Designed for tractor-trailers and refrigerated vans, this compact lock-pin tool replaces guesswork and multiple trips when adjusting tandem axles. A molded rubber face houses a powerful magnet that holds the device in place while you slide the axle to the desired hole, helping you balance weight between drive and trailer axles faster and with fewer interruptions.

How does the magnetic stopper save time when sliding tandems?

The magnet secures the stopper to the slider’s hole so it stays put while you shift the suspension into place, eliminating repeated trips between the cab and the trailer. You can set the tandem at a marked position on the first try instead of relying on a spotter or visual estimation.

• Strong embedded magnet keeps the device attached during axle movement
• No need to jump off the truck repeatedly to check pin alignment
• Faster adjustments at weigh stations and during loading operations

Is the Yoolon tandem slide stopper easy to use alone?

Yes — the tool was made for one-person operation. Insert the stopper into the chosen slider hole, release the parking brake and unlock the slider, move the suspension until the axle contacts the stopper, then re-lock and remove the pin.

• Simple insert-and-slide procedure suitable for solo drivers
• Works with standard tandem slider hole patterns
• Clear steps reduce confusion and speed up the process

Will the magnet stay attached while driving short distances around yard or lot?

The magnet is robust enough to hold the stopper during typical yard movements, reducing the chance it falls off during short repositioning. However, the device must be removed before highway travel to avoid damage or loss.

• Magnet strength sized for yard and short-movement stability
• Not designed for highway use — remove before high-speed travel
• Visible rubber face reduces the risk of being overlooked when preparing to depart

What maintenance or precautions should drivers follow?

Keep the rubber face and magnet clean and inspect the device before each use to ensure secure holding power. Follow the removal warning and store the stopper in a designated place on the trailer or in the cab to prevent accidental highway travel with the magnet installed.

• Wipe off dirt, ice, or debris from the rubber face and magnet area
• Check magnet adhesion periodically and replace if weakened
• Always remove the device before highway driving as instructed

Who is this for: The Yoolon Magnetic Tandem Slide Stopper is ideal for owner-operators, fleet drivers, and shop mechanics who regularly move tandem axles and need a reliable, solo-friendly tool to position sliders quickly. It suits refrigerated trailers, dry vans, and other semi-trailers where accurate axle placement improves load distribution and saves time at scales and during yard operations.
