BZV 100 FS Blind Cylinder for Fire Doors

The blind cylinder BZV 100 FS can be adjusted for door thicknesses between 45 and 95 mm. Thanks to its brass centre, it is suitable for use in fire-resistant doors up to T90 and is fully adjustable. The hole in the fire door for the cylinder lock can be easily sealed with the blind cylinder, which prevents air from being drawn through the hole. Thanks to the black colouring, the dummy cylinder also goes perfectly with dark doors and fittings. Blind cylinders can be installed easily and without drilling in the door.
