A generous trimming allowance ensures flexibility during installation, and the 10-year manufacturer’s guarantee provides additional reassurance.

As this door is prefinished, it is ready for installation, but will require refinishing in the areas you have cut or modified to fit furniture on your door. For what treatment to use on this internal door, we would recommend an oil from either our Treatex Hardwax or Osmo Hardwax range, which are our recommended tried and tested choice of treatments for any oak internal door.
