Mechanism Details
- Fixing
The heavy-duty bearing is through-fixed with M5 stainless steel screws, retention lugs, threaded steel bushes (or optionally four timber screws with no retention lugs), a 45° operating angle, and a non-directional positive mechanism spring. - Certification
FSB ASL® has Class 4 approval under DIN EN 1906 (certificates set to become available by spring 2017). It meets a variety of demands found in public building projects, offering more flexibility for warehouse purposes. - Adaptor Technology
The new adaptor technology used creates a quicker and more simplified assembly on site as the base-rose is screwed to the door leaf first not requiring the cover or handle alleviating the hassle of screwing past the handle shank. The single-sections roses and backplates are precision-fixed using the FSB clip-on technique. The resistance to tensile forces is enhanced thanks to the stainless steel and GFR plastic reinforced base. - Positive Mechanism
The positive mechanism fitted conforms to the DIN EN 1906 standard/Type of Operation A and facilitates an angle of rotation of up to 45°. Its springs provide dependable support for the lock follower spring. The interaction between the two serves to prevent even heavy door handles from sagging. The positive mechanism acts in both directions, moreover, allowing the furniture to be fitted for either “righthand” or “lefthand” operation – which is particularly useful if it ever needs to be converted to entrance-door furniture on site. This benefit also obtains for entrance-door sets with a symmetrical door lever handle. The same applies to modifications as a result of door thicknesses altering: with two female parts and a full-length spindle, on-site modifications are straightforwardly possible here, too.
Product Options
