Summary

For people with mobility issues using a U-Step walker, the cupholder in the U-Step tray may be too small. In addition, placing a cup in the tray cupholder can prevent the tray and basket from sliding under the crossbar when the user wants to use the seat. This attachment provides a holder for cups with a larger base that doesn't interfere with the movement of the tray/basket. It also has slots to accept the handle of most coffee mugs, which frequently don't fit in the tray cupholder.

I used PETG for mine. The bolts are 1/4-20 x 3/4" pan head machine screws with standard nuts.
