Product Spotlight
The Only Hopper Designed for Heavy Rescue
Signature 4 built the Oil Dry Hopper because nobody else had. It solves a real, documented pain point for heavy rescue vehicles — managing absorbent materials cleanly and efficiently on scene. There’s still no direct competitor equivalent. If your rescue builds are missing a smarter solution for oil dry, this is it.
