ABSTRACT:
A modular fastener system for securing conductive cabling to a variety of surfaces and wiring devices. In a strap configuration, a base support includes a pair of standoffs and a connecting bridge piece that define a conductor support channel. The base standoffs include wall fasteners and a plurality of bores having serrated surfaces. A plurality of ribbed protrusions project from exposed surfaces of each base and retainer bridge. A retainer strap includes a pair of standoffs having serrated bores and a connecting bridge. A plurality of serrated prongs extend from the retainer standoffs and align to provided bores at the base and other retainer straps to define further conductor support channels, upon vertically stacking a number of retainer straps to the base and/or each other. In various wiring devices, the base may include a spanner bracket, a fixed or gangeable junction box or a bushing collar. An alternative strap fastener includes a bridge piece shaped to contain pipes and serrated flanges which mate to any of the base supports.
