Southern Folger's range of mechanical detention locking systems have been around for many, many years. In many cases, not much has changed from the original design. Efficiencies in materials and manufacturing processes have streamlined the delivery and brought the products in line with the ASTM criteria, but the designs have remained unchanged due to the fact that they work so well.
There are two reasons for this. The products need to be substantial in their construction, with heavy gauge materials used that can stand up to the rigours of the detention environment. Secondly, the simplicity of their design ensures many years of trouble-free operation.
Mechanical locks supplied by Southern Folger include deadlocks and deadlatches for swinging doors for applications at maximum, medium and minimum levels.
