This is a generic coro backer plate that is used to keep slitted coro flat. There are three versions of the backer plate available, Single, Dual and Triple zip tie. Each version has a zip tie center to center spacing of two (2) inches. The dual and triple versions have a two (2) inch spacing between each zip tie. The backer plates can be placed end to end and the spacing between zip ties is still two (2) inches. The is a unique ridge on the top size that helps keep tension on the zip tie for a firm hold on the coro, which helps maintain the flatness of the coro.
