Installation Notes

1. Confirm the door and panel are monolithic (tempered) safety glass and within 10 mm (3/8″), 12 mm (1/2″) range.
2. Mark hole positions on a plumb, solid substrate, drill, and secure with appropriate wall anchors and the hinge mounting screws.
3. Hang the door on the hinge and close it; use the adjustment screws to level the gaps before final tightening.
4. Check swing and self-close action through the full arc; confirm the door does not contact the fixed panel.
5. 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-9120 fit?

The Z-9120 is rated for 10 mm (3/8″), 12 mm (1/2″) monolithic tempered glass. Always use tempered (safety) glass – never annealed glass.

What is the Z-9120 made of?

The Z-9120’s hinge body is made of solid forged brass, with stainless steel return springs inside. Brass bodies take Zimmor’s full finish program, including PVD coatings for humid bathrooms.

Is the Z-9120 self-closing?

Yes. A spring inside the hinge starts closing the door from about 15° of opening, so the door returns to the seal line on its own.

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.

Do you supply the self closing 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.
