4. The advantages of door roses associated with your designer handle
Door roses for AP door handles are distinguished by their precision manufacturing and solid metal construction of the mounting adapters. The rose cover is pressure-fitted, making it highly attractive on the door leaf.
The backplates have concealed mounting elements which are not visible after installation, significantly improving the handle's appearance. Square, round, oval and rectangular roses are available across the entire range of types: bedroom key, also available in cylinder and bathroom - WC - privacy lock versions.
We asked our internal handles to offer a new high-quality aesthetic proposition. We therefore demanded the same qualities for the door roses associated with the door handles. If you are looking for modern and quick-to-install door roses, you've come to the right place! The door handle allows you to open the door and the roses allow you to secure or lock access to a room.
The vast majority of our door roses are made from Zamak (zinc and aluminium alloy) which guarantees durability. The door handle's manufacturing material will be identical to that of the associated rose.
