WHAT ARE THE DIFFERENT TYPES OF DOOR HANDLES
When buying door handles you will need to know what the different types and style door handles there are available and make sure you are buying the right handle or you requirements. Below we aim to show you the different types of handles available and help you choose the correct one
Lever Latch (first image) is a standard lever handle used on doors where there is no need for any
Lever Lock (second image) is used when the door needs to be securely locked by a key. This type of handle is used with a mortice sash lock and along with being able to open and shut the door the same as the latch version it can also be locked by using a key.
Lever Bathroom (third image) is used when needing to lock a toilet or bathroom. The lever bathroom handle is fitted along with a bathroom mortice sash lock and enables you to lock the door from the inside by turning the snib, but also has a release slot on the outside handle which allows the door to be unlocked in an emergency using a coin or flat head screwdriver. Almost every style of lever on backplate has a bathroom lever version.
Lever Privacy (forth image) is an alternative locking option for toilets and bathroom doors. The lever privacy is not as common as the Lever Bathroom and tends only to be available to match very limited styles of Lever handles on plate. It operates by turning a snib on the inside of the door to lock, but instead of using a bathroom sash lock it use a tubular latch, and when the snib is turned to the locked position the lever is jammed and the door cannot be opened until snib is turned to the open position. There is still a release on the outside which can be opened in case of an emergency.
The lever on rose tends to be slightly more difficult to fit than the lever on back plate due to the fact that the fixings are normally screw holes around the rose which can be a bit trickier to fix the door.
Most of the levers on rose tend to have a screw on rose which covers over the fixings (as lever in above image), this give a nice neat finish as you do not see the fixing screws, and most have a grub screw under the lever which does up and clamps onto the spindle giving extra strength and sturdiness to handle. With most levers on rose you are supplied with bolt through fixings which fit through the handles and door bolting the handles back to back giving a very solid fixing.
These types of handles are not always ideal to fit to existing doors with mortice locks in as there is very little wood left of the door to fix to if there are locks already fitted in the doors. If you want to fit these handles with mortice locks you will need locks that have holes either side of the spindle hole which allows you to bolt through the door.
For locking options you have several different types
Key Locking options for lever on rose you will need to buy keyhole Escutcheons (third image). A
The standard mortice door knob (first image) fits to the door mainly screwed through the back plate to each side of the door and connects together with an 8mm spindle. Some pairs of knobs also have a grub screw under the stem of the knob which clamps on to the spindle to give extra strength to the fitting. Some mortice knobs will have a threaded spindle where you put the spindle through the door and the knobs wind onto the spindle and tighten together each side of the door.
Mortice Door Knobs on Back Plates (image 2) are also available and are generally fitted to the door by screwing through the back plate top and bottom.
