3/4" x 6" Short Brass Slab Penetration, installed within a concrete pad, to be grounded out to the rebar. The reason they are shorter than the other brass penetration is they are meant to be attached to PVC sweeps (under the concrete pad) - and to pull electrical lines through, which will later be attached to either the junction box for your underwater LED lights, or to the uw electrical disconnect for your fountain pump.
