What you need is a tray that spans the poles of the frame. That's what this tray does best. It has adjustable clamps to hold tight to the take-up pole, while the rest of the tray sits atop the remaining poles. The HQ Tool Tray 2 comes with 16 dividers so that you can divide space and organize just the way you want. Better yet, the Tool Tray2 will fit any size frame, regardless of make or model! Measures 8.75″ x 32.25″ x 3.25″. Some assembly required.
NOTE: An Expansion Kit with extra dividers and tabs is also available here.
