small, but quite workable
I used this inside a four by four steel electric box on a trailer to wire the tail and marker lights for a trailer. It was small enough to easily fit in the box, and provided more than enough room for the multiple cables to be wired. The four circuits allowed for right and left brake/turn light, marker lights, and backup lights, with the box ground lug serving as a quality, semi-protected ground for all four. Welding the box to the frame after using stove bolts to fasten this to the back of the box provided a great ground to the frame. The provided spade connectors will fit up to 12 gauge wire if you are careful, and allow the wires to be connected without removing the screw from the block--nice feature if you've ever spent ten minutes searching for a dropped screw.
