This distance for these locks can range from approximately. The variable is the space for the first cut (shoulder to first cut). 092"-.095" for these different lock manufacturers. Wafer dimensions are shorter than the overall plug dimension, permitting the cut to be slightly over or under the original specifications.Ĭut-to-cut spacing is normally. The disc's depths of cut are either all odd or even number cuts to have a sufficient increment to avoid accidental interchange. The flats of the cuts in the key blade are approximately. The wafer chambers are slightly oversized. To accommodate the different spacing and depths, each disc tumbler is approximately. They accommodate popular key bittings used by many companies for specific applications where the locks are often keyed alike. These single-bitted lock mechanism cam locks offer 200 combinations.Ħ50/651 Series cam locks are available with the following key numbers: CH751, 8025, 415A and the LS-300. Each of the 650/651 Series cam locks is supplied with two cams (one offset/one straight), two stop plates and spline fillers to convert the lock to a one key pull style. The key pull can be configured for one or two within the 90-degree rotation. The cam locks are available in four lengths: 7/16", 5/8", 7/8" and 1-1/8". Today CCL produces padlocks, cabinet door locks, desk drawer locks, cam locks, electrical panel board locks, enclosure locks and other specialty lock products including the original Sesamee four-wheel combination lock.įor this article, CCL Security provided information on their 650/651 Series zinc die cast five-disc tumbler cam locks which provide field flexibility to more easily key into an existing lock system. Companies are listed alphabetically.ĬCL Security began as Corbin Cabinet Lock in 1882. For this article, I contacted a few cam and cabinet lock manufacturers to discuss some of their products. Mechanical combination locks, hasp-style cabinet locks equipped with an integrated finger pull and electromechanical cam/cabinet locks also increase security.Ĭam and cabinet locks are continuously being developed and refined to provide solutions for residences, and commercial and institutional facilities. Pin tumbler cam and cabinet locks provide a higher level of security, being configured to accommodate commercial keyways incorporating patented and high security lock mechanisms, interchangeable cores and large format cores. Today, wafer locks are mostly made of zinc alloy die cast using single- and double-throw lock mechanisms. Die casting provided the ability for high volume production, making wafer locks economical. However, early wafer locks suffered from cracking as a result of corrosion of the cast components.Ĭam and cabinet wafer locks appeared after die casting locks became more practical in the 1920s using improved processes. ![]() An advantage of die casting wafer tumbler locks is the fewer number of components required. In 1919, Briggs & Stratton incorporated their own wafer tumbler lock design for automotive lock applications. ![]() The reason is wafer locks need a rectangular chamber with a partial cylinder shape to accommodate the spring.Įarly die cast wafer locks were developed in the first quarter of the 1900s. ![]() Manufacturing wafer locks using lathes and milling machines was not practical or cost-effective the cost of machining the wafer tumbler chambers in a brass lock was high. Although wafer tumblers were invented a few years after the pin tumbler lock, they were not manufactured or marketed in those days. Corbin Cabinet Lock (CCL), founded in 1882 in New Britain, CT, produced early brass cabinet locks equipped with pin tumbler locking mechanisms. Cabinet locks have been around for more than 130 years.
