Table&Chair Dollie Adapter

This is a piece I created for the ULine CHAIR AND TABLE COMBO DOLLY (Item H-4787) to lift the cross-bar for the chairs approx. 3.5 inches in order to add room for wider tables.

I modeled it very simply with the plan to drill my own bolt holes during installation. I may update it in the future to have the bolt holes already in it, but I figured this way it could be adapted for other uses as well.

A very simple design, but it's my first one. If you have any feedback, I'm open to it. Thanks.
