Abstract: Cable Support Systems for supporting an object at a desired distance below an overhead beam or other overhead structure are provided. Novel clamps for clamping to the overhead structure are fitted to support cables that encircle objects to be supported by the cable support systems. The novel clamps have internal methods to support the cables. The cables are then encircled around the objects and fixed relative to the clamp. The distances between the object and the clamps may be precisely controlled.

Abstract: A releasable cable grip for locking a cable within a housing is provided. Levers which extend through slots in the housing are fixed to spring biased wedges that force the cables within the cable grip against bores within the housing to lock the cables relative to the housing. By moving the levers outside the housing against the force of the springs biasing the wedges, the cables may be released relative to the housing.

Abstract: A duct access door for use with ducts that carry cooking vapors and greases is a “sandwich” type door that has inner and outer plates, the inner plate being positioned inside the duct and the outer plate outside the duct with a heat resistant gasket attached to the outer plate. Strategically located bolts draw the plates together at their corners to provide compression of the gasket and prevent leaking of vapors and greases.

Abstract: A fabricated connector for oval shaped cross section ducts is provided. The fabricated connector has two oval shaped connector elements, each of which are formed from two semi-circular rings to which universal connectors are permanently affixed on each end of the semi-circular rings by the manufacturer. The semi-circular rings with universal connectors attached are then shipped to the field where angle pieces are inserted and fixed between the universal connectors of the two semi-circular rings to form the precise shape of oval connector desired.
