24-inch wide x 18-inch high, 1-section Scratch Resistant Height Extender with H-Channel
ARX2418 Height Extenders add 18 inches of height to AR CSP systems. 'H' channel and hinge are included. The ARX2418x1 is normally used as an 'add-on' to increase the width of an existing ARX2418 system by 24 inches. When it's time to break down, AR CSP systems with ARX height extenders installed correctly will still fold 'accordion style' for easy storage.
