Wabash Duraplate Pups

Duraplate Pups

DuraPlate® pup or doubles trailers are specifically designed to reduce your equipment’s total cost of ownership in demanding less-than-truckload applications. These trailers provide superior damage resistance and high strength for load securement and optional decking systems. DuraPlate pup trailers deliver exceptional value for your operation.

ID/Aux Stop Light System The new ID/Stop Light System integrates auxiliary brake light indicator functionality with the upper rear ID lights – providing better visibility of trailer braking.

Damage-Resistant Roof System Anti-snag roof bow design deflects impact to minimize damage. Roof bows are constructed of 18-gauge x 80K galvanized steel to increase strength without adding weight.

Load Securement / Logistics 14-gauge, 80,000 psi galvanized steel logistic seams are available on 16” or 24” centers with logistic seams rated at 1,800 lb.

DuraPlate® Composite Plate Sidewalls DuraPlate panels are constructed of a high-density polyethylene core bonded between two high-strength steel skins to provide unmatched damage resistance and maximum interior width. DuraPlate sidewall panels are made in the U.S.A. and backed by a 10-year warranty.*

High-Strength Floor System Rated at 16,000 lb., the full 1-1/4” oak floor system with bolted crossmember connections provides superior floor strength to support high-cycle loading/unloading and extends floor life.
