Safety Bump® the Solution to Transport Hose

Save your drivers' hands, protect your fittings and hose trays! Safety Bump™ is an alternative choice to the traditional cam and groove caps and plugs, providing a comfortable handle for the driver's hand and a "bump" that extends beyond the hose fittings and ears, protecting them from damage.

Safety Bump® is available in two, three and four inch, male and female models, in a hazardous/petroleum configuration with an anti-static additive, a food grade with a food grade certified composite and a septic configuration, all are made from a glass filled composite.

Safety Lock™ Eliminates Spills. Visually Confirm that Cam Arms are Locked

With proper use Safety Lock™ can prevent spills by keeping the imported cam lock arms from opening as they sometimes can during transport or high use periods. It is an alternative product to the hook and loop straps with an easy-to-install and easy to remove, heavy duty "clip" which clicks into place over the cam arms.
