So he invented the Cheetah Speed System, which is marketed by the Cheetah USA Corp., Salt Lake City (cheetahspeed.com). It consists of three components: a snap-on cover plate that clips to the electrical device, the device itself, which can be a dimmer, switch, or outlet, and has speed anchors on the side, and a poly-carbonate outlet box that has builtin slots with teeth that accept the speed anchors.
The units come in 1-4 gang standard and Big-A sizes, and can be used with metal or wooden studs, different voltages, and telecom devices.
The screwless fixtures are said to cut installation time by 75%. A safety strap covers the entire box, so there is no electrical danger even if the wall plate is removed. There are also no exposed wires and an insulated plastic face.
