Dura Crib Cribbing & Blocking

Our innovative Dura Crib™ products are the safer alternative to wood during stabilization operations. Dura Crib gives you the flexibility to stack and interlock plastic cribbing blocks for almost any type of load stabilization or application in industrial or fire/rescue settings, such as auto extrication.

For over 20 years, Dura Crib products have been lab tested and formulated with a reliable and repeatable formula of recycled plastic for unmatched integrity as first responder stabilization tools, such as shoring cribbing for rescue operations. We offer over a dozen different stabilization blocks, chocks, protection pads, and wedges to help you with simple or complex solutions.

Dura Crib products are labeled with a working load limit to provide valuable safety information to the user during rescue cribbing or stabilization of heavy equipment or machinery during repairs. All Dura Crib are made from 100% recycled plastic and are proudly made in the U.S.A.
