ABSTRACT:
The invention is drawn to fixture stock for producing holding devices. The fixture stock is made from an elongated base plate having side rails along two parallel opposed longitudinal edges to define an intermediate, longitudinally extending space therebetween. An elongated jaw plate is disposed above the base plate and between the side rails and an elongated pad of resilient material is sandwiched between the base and jaw plates, which in turn are bonded to opposite sides of the pad respectively, whereby the base and jaw plates are resiliently connected for slight relative movement. The side rafts include a plurality of anchoring holes perpendicular to the base plate and extending through the base plate, and the side rails also include a plurality of thrusting holes parallel to the base plate and extending through the side rails toward the jaw plates. Preferably the jaw plate is split into a pair of separate portions, separated from each other by a filler strip.
