Non-adjustable anti-theft hangers and locks

Non-adjustable plates: although certain plates in this category have the possibility of position adjusting (oblong-shaped fixing holes), they are considered to be non-adjustable because they do not include a post-hanging adjustment system.

Locks: these systems are used whenever enhanced anti-theft protection is required and in particular when it is necessary to prevent the artwork from being pulled away from the wall through leverage. They are usually attached to the bottom of the artwork.
