Extenders allow one row of product to be displayed with other products hanging behind. They are not so unusual on a gondola unit or two, But this entire aisle is Extender outfitted to reclaim merchandising space and cross sell items related to the mops, brooms and long-handled cleaning hardware behind. These extenders field baskets, but Pegboard and vertical display surfaces were among the first extender outfittings. CLICK the thumbnail for a look at the setup.
