What is `anti-bump` cylinder
The market leading lock and cylinder manufactures shout long and load about the benefits of their cylinders and about their anti-bump characteristics but what is `ant-bump` ?
Bumping relies on the energy being imparted into the bottom pins and that energy being transferred to the top pins and reflected causing a brief separation. OK, a bit simplistic but you understand the principle. It was first thought that damping this action would reduce this form of attack. Pickbuster was a thick oil derivative that acted like a hydraulic ram behind the top pis. It did have amazing resistance to bumping but did not restrict professional locksmiths opening the locks. Since then, additional springing and other devices have been tried and the latest range of locks use various patented or patent pending pin combinations to resist bumping.
What is `anti-snap` snap safe` snap secure cylinders
In reality it is only Euro cylinders that suffer snapping-other cylinders have their own problems. The basic method of making the cylinder snap safe is to fit a weak point along the cylinder length. When attacked, this point gives. Leaving a number of pins behind.
The anti Snap may include a toughened spine system or trapping system to prevent cylinder being manipulated with tools. These all have a variety of skill applied. BS1303 is in reality a durability standard. It defines corrosion characteristics and the number of operations that might be expected in a lock`s lifetime along with testing to resist drill, chisel, plug pulling and twist attacks. There is no picking or bumping tested by the standard. One has to wonder why really. Although I now see sold secure are offering an advanced test level on these products.
BS3621 CYLINDER OPERATED LOCKS
The BS3621 standard is for `lock assemblies` and actual wording in the standard is:
This British Standard specifies performance requirements and test methods for a thief resistant mechanically operated single point lock assembly (including locking plates, fixing screws fitting instructions and protective furniture where appropriate). Thus the kitemark is only applied to that lot as a whole. As the kitemark is applied by the manufacturer that has to put it all together before applying a kitemark.
Mul-t-lock
Mul-T-Lock is widely recognised to have pioneered the concept of the anti-bump, anti-manipulation, anti-snap type cylinder, and it came in the form of the Break Secure range. As its name implies, Break Secure is purpose designed so that the front of the cylinder deliberately snaps under attack at a particular breaking point, leaving a portion intact.
The remaining part of the cylinder sits beneath the surface of the door skin, which means a screwdriver cannot be used to reach the lock mechanism. To continue, a burglar would need to cut around the lock, which would take extra time and increase the risk of being caught. Break Secure was the first of its cylinder kind to make it as difficult as possible for a burglar to enter a building where every second counts. With Break secure the burglar is likely to move on in search of easier pickings. For locksmiths Break secure offers a competitive edge that can help to secure business with security-conscious homeowners.
The benefit to offer homeowners is that the lock can still be operated with the key, even after the handle and cylinder have been attacked. This means that if a burglar tries to gain entry but fails, leaving the cylinder broken, the property owner can still gain access to their property and most importantly the property is still secure.
The Break Secure cylinder has undergone rigorous manual testing by professional locksmiths who have attacked locks fitted with the cylinder using a variety of methods, from hammers to drill. Break Secure cylinders have changed since inception and now, being accredited to a BSI Kitemark scheme.
