Before Installation

It is essential for you to make a few decisions before purchasing, including what finish you want to go for if you wish to install a door handle or a doorknob, what style of handle to go for and lastly, you will need to consider the accessibility of your home. Luckily, our guide 4 Simple Tips on How to will guide you through all these determinants to help you decide on your new handles.

Measuring your door

Perhaps an essential step to take before installing your new handles is to have to hand all the measurements of your door. 

You should measure:

  • The thickness of your door.
  • The backset measurement
  • The size of your current handle. 

The thickness of your door

The thickness of your door may seem unimportant, but various door handles or doorknob styles are only suitable for specific thicknesses. For example, most of our door handles at Hiatt Hardware are ideal for 30-45mm thick internal doors. Therefore, it is always worth checking the product specifications of the handles to ensure you are buying the correct size. 

You also need to take note of whether your door is solid or hollow. It is crucial to be aware of this factor, as some door handles may not include suitable fixings for hollow doors. The product descriptions on our website will always state the suitability of each handle.

The backset measurement

The backset measurement is the distance between the edge of the door and the centre of the spindle hole. Again, it may be clearer to remove the old door handle to take this measurement. 

Taking the backset measurement ensures you purchase the correct size tubular latch, should you also need to install this. For example, many traditional door handles will require a latch with a backset of 45mm (a 65mm case size), whilst others, particularly doorknobs, will require a backset of 57mm (a 76mm case size).

The size of your current handle

When replacing your door handles, you want to make sure your new handle covers any screw holes or marks made by your old handle. Particularly prevalent with lever on backplate handles, you can ensure your new one will sufficiently cover any marks or holes by measuring the height and width of your current backplate. For lever on rose or doorknob, this would be the diameter or size of the rose that mounts on the door.

Installing Your Door Handles

Now that you have all the measurements you need and have decided on your new handles, latches, and locks, it is time to start your installation. 

What you will need

  • Philips's screwdriver.
  • Flathead screwdriver. 
  • Or an electric screwdriver.
  • Your new door handles. 
  • The screws are included in your purchase.

Step 1: Removing your old handles. 

Prop your door open using a wedge or doorstop. By doing this, you can access both sides of the door whilst preventing it from closing whilst you are working. 

Unscrew your existing handles. 

  • For aesthetic reasons, the screws of some door handles may be behind the cover plate. 
  • Should this be the case, remove the cover plate by finding the notch and using your screwdriver to lever it off. 
  • If you are uninstalling a lever on a rose handle, you may need to unscrew and slide off their cover plates to access the screws.  

Step 2: Remove your latch or locking mechanism if you need to replace these too.

Should you need to replace your latch or lock, now is the time to do it OR skip to step 4 if you keep your existing lock or latch. 

  • Remove the screws from the edge of the door, which secures the latch and lock in place. 
  • Remove the existing latch by gently pulling it from the door. 

Step 3: Installing your new latch or lock.

Slide your new latch into the hold in the door where you just removed the old one. The forend plate of the latch should sit flush against the side of the door. 

  • If it is not a correct fit, use a chisel to correct the hole's depth gently.
  • Should the gap be too small, use a small piece of wood to fill it in. 

Ensure your new latch lines up with the strike plate positioned on your door frame.

  • The strike plate prevents any dents or scratches to the door frame.

Screw your new latch into place and repeat this process if you are installing a new lock. 

Step 4: Attaching your new handle.

Push the new handle's spindle through the latch now set into the door. 

Slide your new handle onto the spindle and screw it into place. 

Step 5: Repeating on the other side.

Slide the other handle into place on the spindle and screw it into place. 

  • If you install a bathroom handle, you will now attach the thumbturn using the Allen key provided on the corresponding side of the door. 

Step 6: Testing your door handles.

It is crucial that you now test your door handles before screwing the final pieces into place. 

It is vital to ensure the handles work before closing the door; you may become trapped if they are incorrect. 

Step 7: Tighten up the screws. 

The final step is to tighten any screws to ensure the handle is firmly in place. 

You will also want to tighten the grub screws located underneath the lever to lock the spindle in place securely. 

Give you handle a final test, and that is it! You have now finished installing your new door handles!
