Update – choosing a mortice knob!

After the recent addition of mortice knobs to our online range, we have had a number of requests to explain a little more about how to make sure you make the right choice of door knob for your home. We are always happy to offer some guidance and if you have any questions don’t forget you can always call the shop for some clarification!

Mortice knobs

The first thing you should consider is whether mortice knobs are the correct choice for you. Generally speaking, mortice knobs are a more traditional style of door furniture. In the past, traditional mortice knobs were almost always unsprung – meaning the knob turned freely when not attached to the door. As a result of this, many have remained in this style and do not make use of standard locks and latches, as the spring is not strong enough to return the knob. Most lever handles have a spring behind the handle plate which serves to compliment the spring in a lock or latch, but many mortice knobs do not have this, meaning they need a heavier sprung latch or lock in the door. When you look at our mortice knob selection, you should see it indicated if the knob is unsprung and requires one of our heavier sprung tubular latches.

The next consideration is whether you have room for a knob on your door. Because a knob operates from any angle, whereas a lever handle guides your hand away from the door’s edge, our advice is to always try and use a longer latch (We would say 76mm minimum) when fitting a mortice knob, to give space for hands and to prevent bruised knuckles! You may find that your style of door means there is not room to fit a longer latch (100mm +) and in these situations we would not advise fitting any of the unsprung mortice knobs. We also do not advise fitting them on narrow styled french doors, as there is often not enough space between them to allow comfortable operation.

With all these considerations, you may feel put off from looking at mortice knobs for your home, but please don’t – we just want our customers to feel happy with their purchase. Other than in the situation described above (i.e you have very narrow-styled doors), mortice knobs are a classy and classical way to embellish your door.

As always, if you have any questions at all or want us to run through or guide your purchase, you can call us on 01344 876955, or the freephone number across our site.

    What is the correct way to screw a mortice knob to the door. It seems impossible to drill and screw directly since the handle gets in the way. Should I use a 90degree screw driver or is there a cunning method?

    many thanks

    It sounds like you have a large, face fix mortice knob Jim. Many of our door knobs are concealed fix, which prevents this problem. It should be possible to mark the holes out first and drill the wood before placing the mortice knob over them, which should make it easier. A different design of screwdriver may also be necessary, but it is difficult to say without knowing the tools you have. Sometimes a long handled screwdriver, or a 90 degree one can make it easier, yes.
    If you continue to experience this problem please let us know. I will ask a few carpenters in the shop if they have any further advice and update you here if I find any.

    If anybody else has any other advice it is always appreciated.

    Best Regards

    Excellent advice – although a more thorough description of what a mortice knob actually is (and why it’s called that) would be welcome. And a pity that the link to the actual mortice knob page appears not to be working 🙁

    Hi Mark,

    Thanks for the feedback. We believe the links are working but the page is easily found if you click on our logo then look at the product sections down the side.

    A mortice knob is really a door knob designed to operate a mortice lock or latch. This effectively means it is a “turning” knob, and the standard system on internal doors in UK houses. It is different from centre door knobs, which are fixed and designed for entrance doors, and wardrobe/cupboard knobs which are also fixed but usually smaller. Hope this helps but please call the shop on 01344 876955 if you’d like more info, or drop us an email sales @
