The concept of Multi-Function is to make one bag of components available to produce many different functioning locks (up to 6 different functions in our single bitted lock bag).

Multi-Function bagged cam locks include our patented Wonder Washer, which allows for installation into either wood or metal without the use of a double ?D? punch.
