Installation Notes
- Drill the through-holes in the glass panel to the handle’s hole pattern before tempering – do not drill tempered glass.
- Insert the mounting bolts through the glass and thread them into both handle halves.
- Tighten both sides alternately so the knob stays centered on the hole pair.
- Check the grip is solid with no racking between the two halves.
- Re-torque after the first week of use if needed.
Frequently Asked Questions
What glass thickness does the Z-5311 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-5311 made of?
The Z-5311 is built from brass. Solid metal construction matters on glass hardware – thin stamped parts creep loose under door loads.
What does back-to-back mean on shower door handles?
A back-to-back handle is one assembly: a tube passes through the glass and bolts clamp both sides, so you get a pull outside and a matching grip inside from a single fixing set.
Does the handle need maintenance?
Retighten the set screws after the first week of use and wipe dry after showers. Plated brass tube holds its finish well; avoid abrasive creams.
Do you supply the brass shower handle for wholesale and OEM programs?
Yes – this model is produced in Zimmor’s Foshan factory for wholesale and OEM sourcing: custom finishes, packaging and volume pricing are confirmed per order.
