Case Study: when Hi-Load hinges would have been a better choice

October 8, 2013 by · Comments Off on Case Study: when Hi-Load hinges would have been a better choice 


The hinge on the left is a stainless steel 4″ ball bearing butt hinge spotted on a fire door in the gents’ toilet of a busy Exeter department store.  The hinge on the right is a new stainless steel 4″ ball bearing butt hinge, pictured for comparison purposes.  The top bearing has collapsed, its ball bearings have been lost, the washer can be seen protruding out of the joint like a slipped disc.  The effect of this is that the whole weight of the door is resting on the centre knuckle which has compressed onto the collar below causing them to wear each other away.  The degraded state of this hinge increases the opening force potentially causing it to fall foul of the recommendations of BS8300 (DDA/The Equalities Act).  A Hi-load hinge, such as the Royde & Tucker H102 fixed pin hinge, would have been a much better choice for this door.  Why? 
1. The frequency of use for this door could be reasonably predicted to be very high
2. The width of the door was at least 926mm, a long lever (wide door) exerts more power at its axle (hinges) than a shorter one (or narrower door)
3. The door had a door closer, which increases the “adjusted door weight” thus; a door closer adds 20% to the weight, and a back check door closer adds an additional 75%

GEZE TS3000V door closers – for leaf widths of up to 1100 mm

September 26, 2013 by · Comments Off on GEZE TS3000V door closers – for leaf widths of up to 1100 mm 


The GEZE TS3000V guide rail door closer combines the best features of GEZE’s range for mounting on fire and smoke protection doors up to 1100mm wide;  The guide rail makes for a smoother action than “scissor arm” (or “link arm”) door closers, making it a good choice when meeting DDA (The Equalities Act) recommendations.
– Economical compared to other models of a similar specification 
– Closing force – adjustable EN 1-4
– Adjustable latching action
– Easy speed adjustment on the front of the closer (under slide plate)
– Can be used for right and left swing doors without conversion
– For fire and smoke protection doors (with door leaf mounting with mounting plate)
– Hydraulic end stop and closing speed can be adjusted
Several variants of the TS3000 are available; the TS3000BC has back check, the TS3000EC has closing force adjustable EN 2-3, the TS3000EC BC has power 2-3 with back check.  We also sell the bodies separately if required and all spares and options are available: replacement guide rail & arm, electromagnetic guide rail & arm, mechanical back check, mechanical hold open, covers, mounting plates, replacement chock blocks, end packs, fixing packs and guide rail mounting angles.
