Continuous Geared Aluminium Hinges
The Continuous Geared Aluminium Hinge provides high performance fire resistance.
Sealmaster continuous geared hinges provide a commercially viable alternative to traditional knuckle type hinges.
FEATURES & BENEFITS
Sealmaster continuous geared hinges consist of two full height, paired and geared hinge leaves. Each leaf rotates evenly from top to bottom. Riding on multi Delrin bearings, which provide for extremely low friction operation. The geared leaves are protected by a full length channel cap and include specially formulated intumescent seals which protect the entire length of the hinge and which are discretely fitted.
Sealmaster continuous geared hinges exceed the requirements of BS7352:1990 in ensuring alignment of the door with no drop or binding after 1.5 million cycles on 75kg doors. The gearing avoids the need for undue force to open heavy doors of up to 245kg and eliminates repetitive maintenance of hinges, lippings and frames arising from hinge failure.
Sealmaster continuous geared hinges are available in four versions for upgrading existing door sets as well as for new door sets.
Each hinge is available in standard or heavy duty version according to the weight of the door, extent of expected impact and stress. Standard hinges contain 14 bearings distributed down the height of the door which absorb weight, impact and stress and are suitable for doors up to 125kg in weight. Heavy duty hinges contain 27 bearings and are suitable for doors up to 245kg in weight. Example or order code: HSHD- Half surface heavy duty hinge for high load applications. FMS- Full mortice standard duty hinge for normal load applications. All Hinges are produced from extruded aluminium alloy grade 6063-T6 comprising three interlocking sections in a pin-less assembly. Standard finish is natural anodised with gold or dark bronze available to special order. All hinges are supplied in 2.1m lengths but can be cut to suit the door height.
FULL SURFACE HINGE (TYPE FS)
Designed mainly for upgrading existing door sets and applied to the exposed surface of the door and frame.
HALF SURFACE HINGE (TYPE HS)
Designed mainly for upgrading existing door sets. One hinge leaf is applied to the exposed surface of the door and the frame leaf is applied to the concealed surface of the frame jamb.
FULL MORTICE HINGE (TYPE FM)
This hinge can only be used on new door sets because it requires an 8mm gap at the hanging stile to accommodate both leaves and this is more satisfactorily achieved when the new door can be produced to fit the frame.
FULL SERVICE CENTER PIVOT (TYPE FSCP)
The centre pivot variant of the full surface hinge has a smaller ‘foot print’ and is suitable for use on a wide range of frame details including narrower frame (29mm) or frames set close to an adjacent wall reveal.
Sealmaster continuous hinges have been successfully tested with FD30 and FD60 single action double leaf door sets to BS476: part 22. They have also successfully met the smoke leakage requirements of BS476: part 31.1 in independent tests at Warrington Fire Research.
