No one door handle suits all doors globally. Here's why:
Door Thickness: Doors are of different thicknesses, and handles are made to support certain ranges. A handle for a thin access panel won't work on a heavy, insulated HVAC door.
Backset: This refers to the measurement between the door edge and the center of the handle hole. Different door preparations have distinct backset measurements.
Door Material: Certain handles are more appropriate for some door materials (wood, metal, uPVC).
To fit correctly:
1. Measure your door thickness.
2. Measure the backset.
3. Observe the gap between any mounting holes already present.
4. Determine the type of lock or latch you need.
When purchasing a door handle, always examine the product measurements and specifications to guarantee compatibility with your door.
