The 7553 F90 comes as a complete unit and is ready to install on delivery. It is designed to fit snugly straight into holes in the wall. The surrounding steel frame acts as a cover for cloaking the rough edge of the wall cavity. The model 7553 is delivered with official certification of F90 fire resistance.
The 7553 F90 is ideal for handing over valuables such as confidential documents in briefcases, money and safety deposit boxes, and even major sums of money. It is also suitable for handing over identification documents, receipts, firearms and similar.
?The Wurster 7553 was the first cash hand-over unit in Germany to be certified fire retardant to class F90 by the Material Testing Unit Agency in Brunswick (Braunschweig).
The unit comes complete with wiring and can be installed without hassle into existing holes in the wall. To do this, the inner steel frame is removed and the whole unit is then inserted from the outside (customer side). The opening left, right and at the top between wall and frame must be crowded with not combustible mineral wool. The frames are then screwed on. The unit requires access to a nearby electricity socket on the inside (counter side).
