DF11 is the mechanical Defender® that covers different thicknesses in just 3 heights. It is a patented model with a solid escutcheon that can be adjusted with fixing screws: this mechanism allows it to be adjusted from the outside even when it has already been installed on the door.
It consists of a steel Defender® with a high-strength HRC 53 steel escutcheon (65 x 90 mm), available in 3 heights and 3 security versions (B/C/I). The keyway is protected by a chrome-plated steel rotating washer and the aluminium/brass escutcheon cover is available in 7 finishes.
