“Heavy Duty” is not a subjective term – how to be sure you’re buying quality door handles

September 5, 2013 by · Comments Off on “Heavy Duty” is not a subjective term – how to be sure you’re buying quality door handles

The term “Heavy Duty” is no longer subjective, there are EN standards which define the use and durability of each product. A suite of European product performance standards (ENs) have been developed for most building components, these include a comprehensive range of product performance standards for architectural hardware. Products are ‘marked’ with a six or more digit classification coding which shows in detail just what levels of product performance are being claimed for the item. This classification system enables complementary items to also be specified to, for instance, a common level of corrosion resistance, category of use, door mass, etc. as shown below.en-numbers

The important numbers defining the durability of a door closer for example are the first, second, forth and sixth digits. These are as follows:
Digit 1 – Category of use
Grade 2 – for use by people with some incentive to exercise care but where there is some chance of misuse
Grade 3 – high frequency of use by public or others with little incentive to exercise care and with a high chance of misuse.
Digit 2 – Number of test cycles
Grade H – 200,000 cycles; 10N (load on latchbolt)
Grade X – 200,000 cycles; 120N (load on latchbolt)
Digit 4 – Fire Behaviour – Suitability for use on fire/smoke door assemblies having successfully completed a fire test to EN 1634
Grade 0 – not approved for fire/smoke doors
Grade 1 – suitable for use on fire/smoke doors subject to assessment

Digit 6 – Corrosion Resistance – Level of corrosion resistance to EN 1670 Neutral Salt Spray test and operation of the product at extreme temperatures
Grade F – high corrosion resistance; -20°C to +80°C
Grade G – very high resistance; -20°C to +80°C
Marking – To order to comply with the EN standard each product and/or its packaging are required to be marked with:  
The manufacturer’s name or trademark or other means of identification.
Product identification number.
The six or more digit classification number as above.
The BS EN standard number e.g. BS EN 1154 for door closers
The year and week of manufacture (this may be coded).
CE Marking – To be marked with the European Commission’s CE mark, a product will hold all the required certification including classification code of product, type-testing to EN number, manufacturer’s mark, year of manufacture, EC certificate of conformity etc. which will be verified by the notified certification body.

What is meant by “bolt through” door handles?

June 16, 2011 by · Comments Off on What is meant by “bolt through” door handles? 

Bolt through door handles are the best way to ensure the handles don’t get pulled off in high use settings like schools & offices.  Usually only available on round roses, the bolts go straight through the door AND the lock case or the latch.  It’s essential to check the locks and latches are suitable for bolt through fixings, you’ll be able to see holes in the lock/latch case for the bolts to pass.  Door handles on backplates are not designed to bolt through.

What is a “back-to-back” pull handle?

March 24, 2011 by · Comments Off on What is a “back-to-back” pull handle? 

When pull handles are needed on both sides of a door – for example a double action door which swings both ways – back-to-back pull handles are purchased in sets.  The bolts pass through the door and fix into the handle on the other side using a grubscrew hidden on the underside.  This method makes them very strong and unlikely to loosen over time, like surface mounted pull handles sometimes do.  Back-to-back pull handles can be used on timber doors AND frameless glass doors.  If using on glass, you’ll need to get the glass drilled before it’s toughened.  The usual bolt thread is 8mm diameter (M8), but it’s always best to get the handles before doing the drilling, because if may differ.  Tiny clear plastic washers are supplied for use on glass doors.

The handle description says the handle sets are “bolt through fixing”, what does this mean?

March 13, 2011 by · Comments Off on The handle description says the handle sets are “bolt through fixing”, what does this mean? 

Door handles can be subjected to a lot of force which, over time, can loosen and wobble them free.  Bolt thru’ fixing is the best way of fitting lever handles for a long, maintenance-free life span.  Essentially, the bolts holding the handles onto the door pass right through the door AND the lock case or latch case, and fix into the handle rose on the other side.  For this reason, lockcases and latch cases must be “bolt through fixing” too with holes in the right places (most good quality ones are these days, Doorstuff’s ALL are, but if you’re using your existing locks and latches it’s always best to check them).  It is only possible to bolt though lever handles which are on roses, rather than the traditional back plate style, which are always surface-mounted.  Watch this YouTube video about fitting door handles, it shows how the bolts and latch case all fit together to give a strong finished result.

needs to be opened on a regular basis to allow access for staff but which also needs to discourage the residents from using it, for their own safety.  Therefore it needs to be secure but easily opened daily and opened by anyone in an emergency. Have you any suggestions please?
This situation can be addressed using a maglock to secure the door shut, which is operated by a digital code pad on the side which staff need to access from.  The maglock would be wired into the fire alarm, so that during a fire the door is operated by anyone.  The door itself can have a pull handle on one side and a push plate on the other, or can have a simple latch with lever handles.  The maglock is not something we list here online, but contact us for a quote.

I am unsure which lockcase to purchase for my door handles I am looking order door handles for my new doors, S103 mitred lever BSS/PSS and matching bathroom lock set but could you please let me know which lockcase I need?

You can order the “S103 bathroom set, Duel” (which includes the door handles, bathroom indicator set & bathroom lock case), just select 44mm (or 57mm) for the backset dimension – the usual for domestic doors is 44mm, and as they’re new doors you have no pre-cut holes to measure.

Q: Could you tell me if the AL155 door handle can be used on an exterior door or are they only suitable for internal use?

August 15, 2010 by · Comments Off on Q: Could you tell me if the AL155 door handle can be used on an exterior door or are they only suitable for internal use? 

A: The AL155 is probably more suitable as an internal door handle.  There is a similar one available in Stainless Steel, the S129 which has the dimpled design as well, which would be more weather resistant.
