###### CRASH BOXES

##### Crash boxes

##### Crash boxes

##### Crash boxes provide an incredibly high energy absorption capacity. They operate in parallel with the coupler and are usually combined with anti-climb devices to achieve optimal structural collapse, as they are not designed to transfer high vertical and lateral loads.

##### Product features:

- Non-reversible energy absorption (must be replaced after use)
- Not velocity dependent
- Almost 100% efficiency
- Absorbs the remaining impact after the initial collision
- Shape can vary to fit available space
- The product is used in combination with coupler release/shear bolts to ensure that the coupler is released in a controlled manner and pushes through the towing pocket without affecting the crash boxes or cab structure
