Give your slatwall both the additional strength and a professional look with these aluminium inserts. Without them you will see the standard MDF at the rear of the insert. Also without them you are relying on the cut edge of the MDF slatwall panel to support your slatwall accessories. These inserts fit our panels and are available in either 1200mm wide (suitable for portrait panels) or 2400mm wide (suitable for landscape panels). There are 23 in a pack for portrait and 11 for landscape. These L shaped inserts need to be put into the panel before installation as they are so strong, they can't be clipped in afterwards. Please note not all inserts fit all panels, if unsure if these will fit your panels please get in contact.
