Cardas 3455R Power Connector Plug
The Cardas premium power connector plug features copper blades and clips,
plated with rhodium over silver, for improved electrical contact and
current transfer. Its compact body and secure fit help prevent heavy
power cables from pulling out of the wall. The clamshell opening allows
easy access to the screw-clamp terminals, and the flexible grommet
accommodates cables diameters as small as 0.4", or can easily be removed
for larger cables.
