The Rotary Die Collar is the simplest external catch fishing tool designed for retrieving a fish from the hole.
Die collars are available in two types: type A and type B. They are available in an assortment of sizes, lengths, and connections; and can be custom made to specification.
Type A Rotary Die Collars are manufactured with an integral guide. The guide end of the die collar may be specified as flat, smooth, or cut-lipped.
Type B Die Collars are manufactured with a threaded bottom end for attaching a standard cut-lipped guide or wallhook guide of your choice.
