Fadachai Trailer Axle Stopper — Magnetic Tandem Slide Stopper, 1.5" Pin, Heavy-Duty Steel with Rubber Face

Fadachai’s reinforced magnetic tandem slide stopper is a heavy-duty trailer axle stop that secures a precise axle position quickly and without a spotter.

This magnetic trailer pin stopper is engineered to simplify tandem axle adjustments on semi trucks, dry vans and reefers. Built from carbon steel with a corrosion-resistant powder coat and a thick rubber face anchored by a powerful magnet, the device holds firm against vibration and weather. Its universal 1.5" pin size fits most trailer axle holes and lets drivers set axle position reliably for accurate weight distribution at weigh stations and during loading.

How does the magnetic axle stop speed up axle alignment?

The magnetic face and secure locking design let you set an axle position without a second person. Instead of repeatedly stopping, climbing down and checking the hole, you place the stopper then slide the tandem until it meets the stop. That saves time at weigh stations and reduces the back-and-forth during tight deliveries.

• Embedded high-strength magnet holds the stopper to the axle face for one-person use
• Clear faceplate directions reduce guesswork
• Easy-grip welded handle lets you position the device even with gloves on
• Works with standard 1.5" trailer axle holes for broad compatibility

How durable is the Fadachai trailer tandem slide stopper under road conditions?

Durability was prioritized in the design: heavy-duty carbon steel construction, welded handles and pins, and a powder-coated finish protect against rust and physical stress. The rubber face cushions impact and resists deformation so the stopper maintains a secure fit over long-term use. This makes it suited to wet, snowy, and abrasive environments common to trucking.

• Carbon-steel body with corrosion-resistant powder coat
• Thick rubber cushion resists wear and vibration
• Welded components and reinforced pins for maximum strength
• Magnet plus high-strength adhesive keeps the rubber face attached

Will this fit my trailer and how do I install it?

The Fadachai stopper is designed to fit trailers with 1.5" axle holes, including semi tractors, reefers, and most dry vans. Installation is straightforward: insert the pin into an axle hole positioned one hole before or after your target spot, release the parking brake, then slide the tandem until it contacts the stopper. Removal and repositioning are equally simple for successive adjustments.

• Standard 1.5" pin diameter for common trailer axles
• Insert pin in pre-target hole, release brake, then slide tandem to stop
• Welded handle for quick placement and removal even in cold weather
• Faceplate markings guide correct orientation and use

Is the magnetic stopper safe to leave attached during driving?

The design reduces the chance of the device coming loose while driving: a powerful magnet embedded in the rubber face plus high-strength adhesive keeps the unit in place. That said, standard safety practice is to confirm removal or stowage per company policies before transit. The magnetic base and rugged build minimize wobble and help prevent accidental loss when used as intended.

• Strong embedded magnet and adhesive secure the rubber face
• Stable magnetic base reduces wobbling during adjustments
• Durable construction tolerates incidental contact if briefly left attached
• Always follow fleet safety rules about leaving tools attached while driving

Who this is for: professional drivers, fleet operators and owner-operators who need a dependable, quick method to set trailer axle position. If you frequently adjust tandem slides for weigh stations, mixed loads or regional deliveries, this heavy-duty pin stopper helps reduce time, eliminate reliance on spotters and protect your tandem mechanism from repeated guesswork. It’s especially useful for reefers and dry vans that require consistent axle placement in varying weather conditions.
