Door Straighteners

Door straighteners prevent doors from bending or fixed warped doors caused by heat and humidity. Sugatsune offers 3 types of door straighteners:

  • Concealed straighteners
  • Recessed straighteners
  • “Retrofit’ straighteners

Concealed and recessed straighteners do not have to travel the whole length of a sliding door, only the top 2/3. A “Retrofit” straightener should travel along the whole length of the door and be used in pairs.



Recessed straighteners are to be mounted onto the face of a door, and can be easily adjusted from either the top edge or the back face of the door.




Concealed straighteners are mounted into the door at the time of manufacturing, under the laminate and can be adjusted from the top edge of the door. 



Retrofit straighteners are installed post-production, on the back of an existing door and can be adjusted from the top edge of the door.
