This attachment is ideal for draining residual water from long straight LDH lays. Faster and safer than shoulder draining, it makes draining large diameter hose a quick, one-firefighter operation. It's easy to attach and remove and carries a convenient set of Kocheck® wrenches. After couplings are disconnected, let the water flow out until it stops. Lift the high-grade coupling and lay the hose over the drain attachment roller and feed the coupling through the back of the RollNRack unit. Kick the coupling back with your foot and wheel the RollNRack unit forward. The coupling will clang through the unit. Hose is now manually rolled and coupling is left at 12:00. Remove the drain attachment to transport the hose roll. Load all your rolls of hose in an easy and safe operation with just two firefighters. Never lifting LDH rolls!
