I've rearranged the fittings to not pinch the glass on the backside. There are stress fractures that haven't transfered to the top. The top of the loop is smooth.
Everything is on the underside. Noting is pinching it now and its held in with just the folder over brass points.
To remove / install just slide it up and down the rod with socket setup removed. You may glue it down to the base when you recieve it.
