Aluminium profiles which interlock.
One part is screwed to the frame or panel and the other to the wall. They provide a stable and level means of hanging pictures and mirrors. They are often used by trade installers and display contractors. Sometimes just one strip can be used when it engages with an aluminium frame channel. Packed in a polytube in pairs with 30mm screws and plugs for the wall and 15mm pan head screws for the wood. Ovalled holes simplify levelling. To hang a larger item, use several Z Bar strips in a row to help spread the load.
Available in a variety of sizes for weight ratings of up to 90kg
