Door Trimming
Guidelines

Exterior Doors

  • KEENA exterior doors have near equal reinforced edges on both sides.
  • A maximum of 9 mm may be trimmed from each side (18 mm in total).
  • Where trimming is required, we recommend prioritising the side that will be used for hinge installation.
  • We recommend retaining a 10mm thickness, particularly on the “hinge side”.

Interior Doors

  • KEENA interior doors have a thicker, reinforced edge designed for hinge installation and a thinner edge intended for the lockset.
  • A maximum of 12 mm may be trimmed from the thicker (hinge) side only.
  • Trimming the thinner (lock) side is not recommended, as this may compromise the structural integrity of the door and affect lockset installation.

Important: Always measure carefully before trimming. Do not exceed the recommended trimming allowances, as this may affect the door’s strength, functionality and warranty.
