Original Vintage Plastic Nut

In 1964, Trevor Peck, a wealthy businessman who owned a hosiery factory in Leicester, also became involved in nut manufacturing. He paid particular attention to producing an object less costly than the MOAC. Peter Biven and his brother Barrie introduced Trevor Peck to climbing in 1951 and the three of them formed a formidable climbing team for many years. The credit goes to Trevor for dreaming up the chock. His Crackers were made from knurled round steel or Duralumin bar cut to the required length. He used steel wire, stronger than small diameter rope, for the smallest sizes. The earliest ones, in which the wire ends were locked and silver soldered into a copper sleeve, were definitely in use in 1962. It was only in 1967 that the wires were swaged with the Talurit ferrule system. There was also a nylon version of the Cracker, the Ny-Chock on tape. Trevor Peck deposited the first patent for nuts in 1965. This was later refused since there was already proof that the MOAC predated the Peck device and left the door open for other innovators. The Peck Crackers were not very successful in England but the American climber Royal Robbins, returning from a trip to England in 1966, took back to the USA not only a few samples but also his experience of the art of placing passive protection. In his excellent book, Advanced Rockcraft, a superb photo by John Cleare shows Peter Biven using a Cracker on the Coal Face at Bosigran. Unfortunately, Trevor Peck passed away prematurely in 1969 and was not able to develop his company, Peck Climbing Equipment.
