The DF17 is an adjustable mechanical Defender® with a solid escutcheon and spring-loaded fixing, which makes it extremely easy to adjust, even if spacers have to be inserted. It can also be installed horizontally.
It consists of a Defender® and a high-strength steel escutcheon HRC 53 (65 x 90 mm), available in three 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.
