GEX Aqua Flange 6-45 45cm x 2 pcs New, Unused Item

GEX Aqua Flange 6-45 (for glass thickness 4-6mm, 2 pieces per pack, 45cm length). This is a new, unused item.

I purchased multiple units for earthquake preparedness, as well as to prevent water splashing and fish jumping out, but I have extras, so I am selling them.
