Trumbull HK-3 Meter Box Key/Curb Key/Wrench, Std, Large, & Mueller Pentagon Nuts

Description

Meter Box Key - Curb Box Key - Meter Valve Wrench
The HK-3 has three pentagon sockets, plus a tapered-end prying blade. Socket 1 fits standard pentagon heads, and has a head retention cavity. It also has a slot to operate T-heads of curb and meter stops. The other two sockets both fit the 1-1/16″ pentagon head used on Mueller brand meter boxes. One socket has the head-retention cavity to retain the pentagon head during removal; the other socket has the external lug which engages the lid recess. Both methods assist in lifting the lid of a meter box from the frame. The tapered blade end is designed for prying, or for use as a chisel.
