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%

The H102 hinge is a three knuckle, fixed pin butt hinge. The bearing arrangement in Royde & Tucker H102 hinges accounts for both vertical and lateral loads, as well as spreading the load over as wide a surface area as possible. This design, in conjunction with its unique material and lubricant properties, results in its unrivalled performance.

Taken from Royde & Tucker’s literature, this useful illustration is helpful for deciding which hand hinges are required:-
We are considering your Foldaside 100, but our present sliding folding gear is top hanging and has no bottom guide rail. At the bottom there is a join of two carpets and a metal strip to prevent the edges fraying. The underlying floor is also concrete and it would therefore be difficult to create a 15mm groove in to which to set the bottom guide. Is the bottom guide strictly necessary in this case please?

A: Yes, we stock them in Bright Zinc finish, both left and right hand. The Royde & Tucker H105 lift off hinges are handed so we need to know whether it’s Left or Right hand, and which finish you prefer - there’s Satin zinc, Electro-brass, RAL colours, Simulated brushed stainless, Brushed stainless and Polished stainless? The delivery lead time for for finishes other than Bright Zinc is typically around 3 - 4 days.
I am trying to find H086 - 85 x 76 x 3mm lift off hinges. Our doors are 35mm, would these hinges be suitable for that?

The H086 Royde & Tucker hinges are available from us in BZP (Bright Zinc Plate) and also a wide range of other finishes. 35mm is the minimum door thickness which these hinges will suit. They are handed left or right.
