HK-3 Pentagon Hand Key

The Trumbull HK-3 Pentagon Hand Key has the most number of sockets among the other Trumbull pentagon hand keys. It comes with three pentagon sockets plus a tapered end prying blade. Socket 1 fits standard pentagon heads and features a head-retention cavity that is helpful during head removal. Because it comes with a slot, it works well with T-heads of curb and meter stops.

On the other hand, the two other sockets of this Trumbull hand key fits 1-1/16” pentagon heads used on Mueller meter boxes. One of these sockets come with a head-retention cavity, while the other has the external lug that engages the lid recess. Using this hand tool makes it more convenient to lift the lid of a meter box from the frame. 

In addition to the heads, the tapered blade end comes handy in prying or for use as a chisel. This product is made with a medium carbon steel investing casting and a plated finish. It weighs 1.0 lbs and is covered by a limited lifetime warranty.
