Automatic multi-point locking system BS 3700

With its self-adjustment feature, the innovative automatic multi-point locking system BS 3700 allows fabricators to make considerable time and cost savings: the intelligent design of the locking elements and matching frame parts means there is no longer any need to make readjustments on-site at any point in the door's product life cycle. If the locking elements come to a standstill before reaching the end position, they are locked by a back-pressure safety device to reliably hold the door leaf in position. The automatic 20 mm clearance between the hook bolt and main lock bolt ensures a high level of security. The door also opens effortlessly and smoothly thanks to the low-friction combination of materials.
