The Diamond link is an excellent deterrent with good physical protection for internal installations.
The Diamond range gets it's name from the disctinctive diamond shape of the steel linkages. As the Extendor range is made with no external rivets showing the installation looks neat even in a domestic environment.
The more robust Classic product provides protection for higher risk areas.
The classic system has been designed for situations where a greater degree of strength is needed. Instead of a single diamond shape linkage system, the Classic has double the amount of linkages giving greater all round security. Although the Extendor range has been designed for internal use, as can be seen from the shop front pictures here, it can be just as effective fitted externally also.
From the outside, the Elite range looks no different to the Classic. However, there are some very subtle high security additions to this range. Many of the cross linkages are hardened steel making them invulnerable to hacksaw and light cutter attack. Hidden within the uprights are steel rollers which foil attempts to cut through the uprights with the likes of a hacksaw. At the time of writing, the Elite range is the only range of folding grilles which has been accepted by the Ministry of Defence.
Extendor can manufacture specials for almost any application. A common request is for securing file servers. A complete room can be fitted out with these grilles allowing movement of air whilst still ensuring complete security of your valuable computer equipment.
