  STEP CHOCKS and WEDGES

Updated June 5, 2025

Step chocks are used for stabilizing vehicles and other unsteady objects, often in conjunction with wedges. They are carried on Rescue-1, Rescue-2 and Rescue/Transport-11.

Aluminum wedges have a variety of uses. They can be used to tighten up small spaces between step chocks and unstable vehicles, they can be used to drive into cracks to enlarge them for the insertion of pry bars, and they can be used as a cutting / prying tool when attached to a Halligan tool.

On a Halligan tool to use for pry-back purposes.
Rescue-1: Step chocks and wedges are stored in compartment No. 6.

Rescue-2: Step chocks and wedges are stored in compartment No. 7.

For more information regarding the use of step chocks and related accessories, please visit the Technical Sheet, Overturned Vehicle Stabilization.
