Series 28 one from Camlocks is noted for its excellent security, key control and supreme build control. The USP of this series is the 7 pin version award winning and patented Octagon mechanism. This brass device is not only durable and reliable but allows for about 500,000 different key combinations as well. It has a chrome plated outer body and added security is ensured through its anti-drill center. The cam lock comes in a variety of sizes: 13mm, 18mm, 25mm and 30mm. To ensure users enjoy optimal key control, key registration is possible for all 'keyed alike suites'. All the versions of the cam lock, except the 13mm, are equipped with a body, nyloc type tail nut and two keys for each lock with easy-to-identify blue plastic key covers.
