Sliding Shower Door Bottom Guide
Replacement bottom guide for a bypass/sliding shower door: a 46 x 22 x 15 mm block that screws to the track with two countersunk M3 (#6) screws and carries the door's bottom glass edge in a 7.2 mm channel sized for 1/4 in (6.35 mm) glass. A V-shaped lead-in opens the channel to 12.7 mm at the rim so 5/16 in and 3/8 in glass still ride about 5 mm deep, and flared ends in plan view guide a drifting door back in; the counterbored screw holes also drain the channel.
