4. The advantages of door escutcheons associated with your designer handle
Door escutcheons for AP door handles are distinguished by their manufacturing precision and the solid metal construction of the mounting adapters. The escutcheon cover is fitted by pressure, making it very aesthetically pleasing on the door leaf.
The backplates have concealed mounting elements that are not visible after installation, which significantly enhances the aesthetic of the handle. Square, round, oval and rectangular escutcheons are available across the full range of types: the bedroom key, also in cylinder version and in bathroom – WC – privacy turn version.
We asked our interior door handles to offer a new aesthetic and high-quality proposition. We therefore demanded the same qualities from the door escutcheons associated with the door handles. If you are looking for door escutcheons that are modern and quick to install, you are in the right place! The door handle allows you to open the door and the escutcheons allow you to secure or lock access to a room.
The vast majority of our door escutcheons are manufactured in Zamak (a zinc and aluminium alloy), which is a guarantee of durability. The material used to manufacture the door handle will be identical to that of the associated escutcheon.
