Posted: Mon Feb 08, 2010 10:51 pm
Here is a 7 pin BEST small format interchangeable core lock. There Core is made up of 3 parts, the plug the control sleeve and the shell. A core key is inserted and turned 20 degrees clockwise which turns the control sleeve and retracts the control lug. Ken Peterson makes a set of IC tension bars to assist in picking the core to the control line. The tension bar is inserted into the holes in the bottom of the control sleeve to put more tension on the control sheer line.
Core with control lug retracted, core can be inserted or removed from housing.
