AltitudeCraft Tandem Slide Stopper for Semi Truck

Key Points:

• Set your stop once, slide once: No spotter needed. Insert the stopper as many holes from the end of the slider box as you want the tandems to move, on the side they move toward. Slide until the slider box stops against it, then lock the slider pins.
• Built-in magnet: The magnet holds the stopper against the rail while you slide the tandems. It is a positioning aid, not a travel lock, and it is not designed to stay on the rail while the trailer is moving. Remove it before you drive and confirm all locking pins are fully engaged.
• Carbon steel: Carbon steel body with a black powder-coated finish. The pin diameter is 1.5 in (38 mm), and the base plate has a silicone pad.
• For sliding tandems on dry van and reefer trailers: Made for semi trailers with a sliding tandem. Not for fixed axles. Check that your slider-rail holes fit the 1.5 in (38 mm) pin before you order.
• Warranty: 1-year warranty; a 3-year extended warranty can be applied for on altitudecraft.com.

How to use, in six steps:

1. Decide how many holes you want the tandems to move.
2. Insert the stopper that many holes from the end of the slider box, on the side the tandems move toward.
3. Set the trailer brakes (red knob out) and release the tractor brakes (yellow knob in). Unlock the slider pins.
4. Slowly move the tractor until the slider box stops against the stopper.
5. Lock the slider pins. Check that every pin is fully through the rail holes.
6. Remove the stopper, then do a gentle tug test before you drive.

The stopper only helps you stop at the target hole. Weigh the truck to confirm your axle weights.

In the box: 1 x tandem slide stopper.
