This information is for your guidance only, if you are unsure of which types of spare parts you need we recommend either sending us photos or requesting a site visit.

Glass sealed units


Measurements required for glass sealed units include the total width in mm, the total height in mm, and also the total thickness in mm. We will also need to know if you require toughened glass or coated glass units. If in doubt ring us and remove the guess work by letting us measure them for you.

Door lock identification


Most locks have identification markings along the face plate, the

most common locks being Mila, Fhur, Roto, Avocet, Ferco, Winkhaus, Lockmaster, Maco, Yale, Sigenia.

If there are no markings we recommend a site visit.

Measurements required include; most important, lock spindle to centre of the round part of the lock cylinder, also measure from lock spindle to rollers and hook locks. We will also need the lock back-set measurement this is measured from the lock spindle to the front of the face plate.

If you are in any doubt please ask us for advice.

A free site visit from one of our engineers can rule out costly mistakes, we can identify your locks,units etc... and give advice on fitting them yourselves. Many items can be fitted easily with a small amount of diy experience, if you get into trouble whilst carrying out a repair we are always there on the end of the phone!

Alternatively and for peace of mind let us complete the repairs for you.
