Special Finger (for Crockmasters) for holding felts

£76.00

The Special Finger for CrockMaster is a specialized attachment designed to securely hold felts during crocking tests for dye transfer in leather. Crocking tests, such as those performed with the James Heal CrockMaster, assess the colorfastness of textiles by measuring the amount of dye transfer when subjected to rubbing. The special finger ensures the felt remains in place, allowing for consistent pressure and movement during the test, which is crucial for accurate and repeatable results. This finger does not fit on older models of the CrockMaster, specifically the 255 and 255A.
