Description & Fitment

The ATB A-DP57 is a non-slip strut grip deck plate step that mounts on a semi tractor's frame behind the cab. It gives you a solid platform to reach trailer hoses and connectors and for routine checks. It is 2"H x 7.5"D x 34"W in .125 smooth aluminum and comes with ATB's M3120D clamp mounting kit.

Fitment & Compatibility

How to choose: measure the top of the frame behind the cab where the step goes and check the 34" width and 7.5" depth fit there.

Frequently Asked Questions

Will it fit my tractor?

It is made for semi tractor top-frame mounting. Compare your frame top with its 2"H x 7.5"D x 34"W size before ordering.

Is a mounting kit included?

Yes. The M3120D clamp kit comes with it: two mounting clamps, four 5/16" x 1" bolts, four nuts and eight washers.

Does it need drilling?

No. The deck plate is predrilled and clamps to the frame platform with the M3120D kit.

How does it ship?

By freight from the ATB factory in Blanchard, ND, with lift-gate delivery available. For Alaska, Hawaii or Canada, contact us for a freight quote before you order.

What should I check when it arrives?

Check it before the driver leaves: look it over for dents, scratches or shipping damage, note any damage on the delivery receipt and send us photos.

  1. Check all parts against the parts list and make sure there is room to mount the deck plate.
  2. Set the deck plate on the frame platform to confirm it fits there. The holes are predrilled.
  3. Fit both mounting clamps one at a time, insert the four bolts and run the nuts on lightly.
  4. Square the deck plate and tighten all four nuts securely.
  5. ATB warns: never drill the top or bottom flange of the truck or trailer frame, and never weld mounting brackets to the frame.
