The body is machined from solid forged brass, with stainless return springs and self-closing action from 15°. It is available in Zimmor’s full finish program (PVD included) to match the rest of the enclosure hardware. Wholesale buyers commonly source this model as a heavy duty shower hinge.

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-9140 fit?

The Z-9140 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-9140 made of?

The Z-9140’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-9140 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.

Can the door position be corrected once fitted?

Yes – loosen the adjustment screws, level the door against the fixed panel, and re-tighten. Do the check with the door closed so the gap line reads true.

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.
