A1 introduces the first multipurpose fixture for servicing Corbin Russwin Interchangeable Cores, the A-1 Model TB5. The control lug can swing out for pinning or checking of the control shear line, and the tool holds the IC secure for the safe staking or removal of the spring cover. It allows for pinning of both 6 & 7 pin cores. Information: www.demanda1.com
