Shutters are used to close shops , garages and warehouses. These are all places which house valuables and are therefore particularly at risk of theft. The shutter is the first protective barrier and the most frequently attacked point. For this reason, this is the first point to look at in order to increase security. Before assessing more challenging and costly solutions, you may wish to consider replacing the weak standard lock with an armoured lock. The new Viro 1.8270 Series patented and armoured locks makes the operation particularly simple .

Except in particular cases, the locks fitted originally on the shutters are basic, economic models and provide with little resistance. In particular, there are 3 weak points:

The case, which is made of thin, cut and bent sheet metal.

The dead-bolts, which are also usually made of bent sheet metal, which can be easily forced with a lever, such as a crowbar.

The cylinders, which lack any form of protection and often protrude, so they are easy to attack with chisels, hammers, drills and other burglary tools.

The new Viro 1.8270 Series armoured locks for shutters eliminate all 3 of these weaknesses:

The case is made of thicker steel (2 mm)

The dead-bolts are made of riveted sheets of solid steel 6,5 mm thick

The cylinder is protected by a pull-resistant security escutcheon fitted with a rotating drill-resistant plate.

The rotating plate is the most effective solution against drilling as it not only prevents penetration of the drill bit, but, by rotating with the drill bit itself, it prevents it from gripping and moving forward, thereby also preventing internal mechanisms from being damaged.

The entire lock is also protected by a 2.5 mm thick steel plate fastened outside, so as to enclose the steel sheet of the shutter between the body of the lock and the plate itself, thus forming an extremely resistant” sandwich”, and making it particularly difficult to pull of the lock.

The security can be further increased by appropriately selecting the cylinder. The lock can house any European profile cylinder, even a high security type. The model which best suits your needs can therefore be selected. You can use either a half cylinder, if it is only necessary to open and close from the outside, or a double cylinder, if it is to be operated also from the inside.

Replacing a normal original lock with the new Viro armoured lock is particularly easy, as the centre-centre spacing of the fixing holes is the same as for the most commonly used models. It is not therefore necessary to drill new holes in the shutter, but simply widen the existing ones so as to be able to use the case-hardened drill-resistant fixing screws with pull-resistant heads (supplied) with a diameter of 6 mm (instead of the 5 mm commonly used). The only operation required on the shutter is the widening of hole through which the old cylinder passes, which is necessary in order to house the new security escutcheon. To simplify the operation an accessory is available which allows you to drive the drill in the exact position.

The compatibility between the new and the old locks is guaranteed by the fact that Viro 1.8270 Series locks are available both in the version with a double dead-bolt, for mounting in a central location, and with single dead-bolt, for mounting in lateral position, either on the right or left-hand sides.

Furthermore, the locks of this new series can also be installed vertically, for example on metal doors (those found on secondary entrances, such as taverns, cellars and garages) and, using a double friction cylinder, they can also be connected to a remote electronic drive system.

Increasing the resistance of a shutter is especially simple and effective  with the new Viro armoured lock. An excellent lock is in fact the first step towards improving the security of your shop, warehouse or garage.
