I bought a gun security cabinet off of craigslist. The guy I bought it from was not using it as a gun cabinet and had since lost the holder thingies. I did some searching last night and, for the life of me, could not find any, nor could I find what they are actually called. What are they called? Where can I order them? (I am pretty certain that when I find out the propper name I will be able find them online.) Thanks.
