A wrapping device for binding and holding together a plurality of items, such as cables, and feature a clip or cleat which securely holds a length of longitudinally resilient cord or the like wrapped in tension about said items. In one form, a plurality of cleats are integrally molded together in series to facilitate their use.

An explosionproof fixture hanger is disclosed which is adapted to support a depending explosionproof fixture in a manner providing resilient cushioning and lateral flexibility. An annular housing, formed for mounting on a junction box, is fitted with a laterally resilient stem. The stem protrudes through a housing hub and is telescopically carried on a resilient member within the housing for limited axial movement. The inner surface of the housing hub and the outer surface of the stem define a pressure-dissipating explosionproof joint. A lighting fixture is mounted at an opposite end of the resilient stem.

The threads by which a cover is secured to a housing for electrical elements are positioned on mating conical surfaces. The taper of the threaded conical surfaces is sufficient to permit bringing the threads on the cover down over most of the threads on the housing by simply axially mating the cover with the housing. A few turns of the thus positioned cover brings all the threads into engagement to provide an ''''explosionproof'''' closure, e.g., with six full threads engaged. Stop-lock means prevent advance of the cover to zero clearance between threads and prevent inadvertent partial unthreading.
