Do I need to lock every internal door?

Thu, February 07, 2013


Putting it simply no. The only internal doors you need to lock are the bathroom doors. For the other doors all you need to use are latches rather then sashlocks.
The latches which are tubular are cheaper and also easier to fit then the sashlock.
In addition to this the latches do not require Escutcheons when they are used with a lever on rose so money is saved there too.
At the end of the day it is personal preference as to which you go for but the cheaper latch is viable alternative.

What finishes work outside?

Thu, February 07, 2013

Most finishes such as chrome or stainless steel will work outside but problems arise when you want to use brass outside. The lacquer while fine for internal use is quickly eroded by the elements and the finish will tarnish. The brass used must be PVD in order to avoid this happening. This is a process that ensures the brass will not diminish for 25 years. It will still need to be cleaned to ensure the polish is seen but once maintained it will do fine. The others just need to be cleaned. and they will maintain their finish.

Welcome to our door and window hardware blog. We will attempt to cover a wide range of issues which may be of interest to the construction sector as well as architects and interior designors as well as anyone interested in DIY and home improvement. Let me know if you would like me to cover a particular topic and we’ll do our best to cover it.

Mortice Knobs

Mortice knobs are an aesthetic addition to any door. There are however some points that should be considered before choosing knobs. With the correct consideration the functionality and beauty of your door furniture is guaranteed.  

It is important to bear in mind when choosing knob furniture that more manual dexterity is required to operate a door knob whereas a lever handle can be operated by an elbow or hip. They may not be ideal where very young children or older people use the doors frequently.  

Not all doors are suitable for knobs. Check that there is enough timber in the mid-rail area of the door. 

Knobs require a lock (locking with keys) or latch (non-locking) with at least 100mm of distance from the edge of the door to the centre of the knob. This is to give clearance for knuckles from hitting the frame as you turn the knob. Lever handles normally get away with a 63mm or 76mm backset. This is not generally enough for knobs.  

As with lever on rose furniture, when using with a sash lock you will also need to purchase a matching escutcheon (key hole cover).

When using with a bathroom lock, you will also need a matching turn and release (thumb turn)

Ask our staff if you need any further information. We are delighted to answer any queries you have on this or any other subject.
