Fingerstock
Fingerstock products are ideal for high cycling applications requiring frequent access. Over 350 standard shapes are available, as well as cut to length and modified standards. Fingerstock offers superior performance at elevated temperatures. The standard product is offered in copper beryllium (CuBe) but phosphor bronze and stainless steel are also available. Custom designs are available to meet specific applications.
