Made of high quality cold rolled steel, Size: 43 x 19 x 2 mm, Package includes: 10 Pairs Flush Mounting Brackets (Pack of 20) The wall locking brackets with countersunk and symmetrical screw holes allow, by completely hiding the screws, that there is only a very minimal gap against the wall. The furniture connectors can be used individually for small pieces of furniture. For larger or heavier furniture, multiple mountings are recommended. Interlocking design allows for repeated installation and separation. When you need to separate the nested items for cleaning or other reasons, simply lift it from the brackets. Hanging loops are ideal for attaching picture frames, artwork, display paintings, posters, headboards, clocks, mirrors and much more.
