Abstract: An improved input adapter for electrically connecting input leads with the bus rails of a bus bar system. Connection at any desired location along the bus rails is made possible without drilling holes in the bus rails by an arrangement in which contact plates are held in an adapter housing facing and in position for contact with the bus rails, a clamping arrangement for electrical connection of each contact plate with its corresponding rail, including a U-shaped clamp with clamp ends formed at the free ends of clamp side legs and engaging behind the bus rail, a clamp screw extending adjustably through a threaded hole in a clamp cross portion to connect the contact plate and bus rail, the contact plates having threaded holes in portions away from the clamps for screw attachment of the input leads.

Abstract: A detachable clamping bracket for securely retaining tubes having axially movable cables therein comprising a base member attachable to a wall, the base member having a contoured arm with a concave surface and a hinged bracket arm having a concave surface which, in combination with said base member arm, is adjustable to a closed position wherein the tube is securely supported by said concave surfaces. At least one band is disposed laterally with respect to said base member and bracket arms and firmly attached to said base member, which band is adjustable to a closed position in which it encircles and securely supports said cables.
