Hi! Our shower sliding door came with the house, it was probably installed in 1986 since that's when the house was built.. No idea who the manufacturer is. Little piece is about 1 inch and it's got a hole in the middle where a tiny little plastic screw goes through and inserts ? to the bottom of the sliding glass door. Thank you!!!
