Installation Notes
- Confirm the door and panel are monolithic (tempered) safety glass and within 6 mm (1/4″), 8 mm (5/16″), 10 mm (3/8″) range.
- Mark hole positions on a plumb, solid substrate, drill, and secure with appropriate wall anchors and the hinge mounting screws.
- Hang the door on the hinge and close it; use the adjustment screws to level the gaps before final tightening.
- Check swing and self-close action through the full arc; confirm the door does not contact the fixed panel.
- Wall substrate must carry the door weight – tile over drywall needs backing or through-bolts. Professional installation recommended.
Frequently Asked Questions
What glass thickness does the Z-8320 fit?
The Z-8320 is rated for 6 mm (1/4″), 8 mm (5/16″), 10 mm (3/8″) monolithic tempered glass. Always use tempered (safety) glass – never annealed glass.
What is the Z-8320 made of?
The Z-8320’s hinge body is made of solid forged brass. Brass bodies take Zimmor’s full finish program, including PVD coatings for humid bathrooms.
What does the adjustment screw control?
It moves the glass cup relative to the back plate, so the door gaps can be leveled after hanging. Make final adjustments with the door closed, then lock the screws down.
Can I use this hinge on a heavy frameless door?
Yes, within the rated glass range. For heavier leaves, step up to the heavy-duty series or add a third hinge point so the load splits across the leaf.
Do you supply the rectangular shower hinge 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.
