Pinning kits are available from the core producers and LAB. Top pins, build-up pins and master pins are normally brass. This will optimize the life expectancy of the keys and the cores. Use nickel silver bottom pins when using nickel silver keys. The recommendations are to use brass bottom pins when the cores are operated by brass keys. The pin shapes and composition materials affect the operation and life expectancy of interchangeable cores and the keys. Brass IC pins with a radiused nose for Interchangeable Cores that will be operated with brass keys.015” flat nose for all other interchangeable cores except BEST. Nickel silver material with the radius blended into a +/.Flat nose, nickel silver material pins designed specifically for Best Interchangeable Cores.Schlage has the Everest.ĭepending upon the manufacturer and the key material, there are three different pin types for interchangeable cores. For example, Medeco has KeyMark Interchangeable Core. These specialized cores are manufactured to the basic outside dimensions allowing interoperability between manufacturers interchangeable core lock housing products. Some of these manufacturers offer higher security and patented key control. Manufacturers of interchangeable cores include Arrow, Best Access, Best Security, Corbin Russwin, CX-5, DORMA, Falcon Lock, GMS, Ilco, KSP, Medeco, Mul-T-Lock, PDQ, Sargent Lock, Schlage Lock, Ultra Security and Yale Lock. When discussed, I will list manufacturers alphabetically. 021” increment.įor this article, unless otherwise specified, I will be discussing interchangeable core products based on the Best A2 system. 0125” increment between the pins lengths. Just some background information: Best developed the A2, A3 and A4 systems to provide expanded keying options when setting up their interchangeable core systems. To cut a key requires a 90-degree included angle cutter, and cores are not as forgiving as conventional lock cylinders. 115” diameter for conventional lock cylinders. Servicing interchangeable cores require specialized tools to ensure smooth operating locks and keys, than conventional lock cylinders. The small-format interchangeable core (IC) is regarded as the “universal” lock mechanism throughout the commercial door hardware industry.
