Description Introducing our lineup of extensions organizers! Each individual set includes the larger “head” side to fit the drive side of (6) chrome extensions as well as shafts to support the other end of your extensions. Our MagAttach holders feature magnets on each side to interconnect with our full line of MagAttach magnetic interconnecting holders. We have also put magnets in the base to prevent them from sliding around when drawers are opened and closed. Each extension holder support also features two base magnets. Dimensions/Fit: Notes: *3D printed parts do vary slightly from piece to piece. ** Tools shown in images are NOT included. This is for the tray ONLY.
