FSB is re-uniting what was once one with a comprehensive range of mortice locks. In pre-industrial times, after all, lock and hardware formed a single unit. The two components became detached as it were in the course of industrialisation – and their separation was sealed by a series of industrial standards.
Together with its subsidiary, Sächsische Schlossfabrik SSF, the Brakel firm has now reembraced the concept of functional/technical unity and purposefully coordinated lock and hardware requirements with those for architecture: the upshot is a range of locks that are fully geared to the requirements of modern public project construction and form an optimum whole in conjunction with FSB hardware that would pass any test. All locks bear the CE kitemark, are approved under EN 12 209 and either DIN 18 250 or 18 251-1 respectively and are optionally available in an Fh variant. The mortice locks for flush doors thus ideally complement AGL®/AGL® Fh heavy-duty fittings boasting a sophisticated positive mechanism that ensures the handle remains perfectly horizontal when at rest.
ES/FH 19 and ES/FH 24 mortice locks with sound-damping working parts
SSF is introducing a new generation of mortice locks featuring a technology for the working parts that is unique to the market with its ES/FH 19 and ES/FH 24 series. The latch and lock bolts combine steel castings with injection-moulded plastic guideways and holding elements. This combination is conducive to excellent kinematic properties and good sound damping both in the lock itself and in the interaction between latch bolt and striking plate. Locks from either series can optionally be supplied with latch and lock bolts in nickel-plated die-cast zinc. Lock models in the ES/FH 19 series come with a forend in silver-lacquered steel as standard, those in the ES/FH 24 series with a forend in stainless steel. The self-tightening follower, follower plate and bushing sleeve are made of galvanised steel. Whereas models ES 19 and ES 24 are supplied as heavy-duty locks as well as in warded key and bathroom variants, FH 19 and FH 24 locks meet all requirements for fitting to fire safety doors as laid down in DIN 18 250. There is a choice of forend designs to ensure optimum adaptability to the door leaf and to the hardware used, to wit stainless steel, silver-lacquered steel, hammer gilded or white. Their appointment levels, high quality and rugged design give SSF locks a unique price/performance ratio for locks in this price segment.
Mortice locks in the 50-to-55 Series with optional angle adjustment of the lock follower and/or stop works
SSF 50-55 Series locks are optionally available with either a device for adjusting the angle of the lever handle or optional stop works. The angle adjustment option yields a visual enhancement. DIN 18 251-1 states that the lock follower may be supplied and assembled with an angle adjustment of max. 2º upwards. The consequence of this, however, is that visual shortcomings emerge at the assembly stage – notably in the case of geometrically linear lever handle forms, very much to the annoyance of users who lay store by details and to whom a tidy looking door with strictly horizontal lever handle is paramount. SSF 50-55 Series locks make up for this deficit through the option of placing the lock follower at an angle. With the lock and lever handle fully fitted it is possible to move the lever handle up to 3º downwards by turning a screw in the forend and in this way offset the angling provided for in the standard.
Tamper-proof stop works make the lock even more secure. As long as the dead bolt has not been thrown it is always possible to use the likes of a credit card or similar device to push the latch bolt back by exerting pressure on the bevel, thus allowing the door to be opened. To guard against this means of opening, SSF 50–55 Series locks may if so desired be fitted with “stop works”. When the door is closed, the latch bolt is locked and hence cannot be tampered with. Where entrance door furniture (lever handle on inside, dead knob on outside) has been installed, the door can be opened with the handle from the inside – assuming it hasn’t been locked – and with a key from the outside. In both cases the stopping action is disabled and the latch bolt is withdrawn. Locks with stop works have a wide variety of potential applications in conjunction with the appropriate hardware.
