How to clean the laminate?

All household detergents which do not contain so called friction material can be used for maintenance of the laminate (do not use e.g. Cif cream).

To which doors the door closer reinforcement can be used?

Strengthening of the door closer is an essential element used for the door closer mounting. The strengthening is a wooden structural component, which at the production stage is, at request of the Customer, placed along the top edge of the leaf. Strengthening of the door closer can be used for most types of KMT doors. The exception is KMT CLASSIC class 3 type due to the mounted steel frame that prevents adding additional wood element.
