- Tighten evenly until the washers seat against the glass.
- Hang a wet towel at mid-span and check the tube does not rotate or slide.
- Re-torque the set screws after the first week of use if needed.
Frequently Asked Questions
What glass thickness does the Z-5321-18 mount on?
It mounts on 6 mm (1/4″), 8 mm (5/16″), 10 mm (3/8″), 12 mm (1/2″) tempered glass. The through-glass holes are drilled before tempering, so confirm thickness and hole pattern with your fabricator early.
What is the Z-5321-18 made of?

Can the tube be ordered in a custom length?
Standard lengths cover most door sizes. For non-standard hole patterns or oversized doors, ask Zimmor sales about custom tube lengths.
