So you're looking at glass door clamps for 8-12mm tempered glass, and we've been supplying these for years to folks doing shower enclosures and office partitions—the JL-711 model is pretty much our go-to for that thickness range.
Most buyers go with the 50x50mm size for heavier doors, though the 45x45mm works fine for standard shower screens and won't look oversized on narrower panels. Suface finish really matters for matching existing hardware, so we carry chrome, brushed, matte black, and golden options—matte black has been surprisingly popular lately for modern bathrooms.

We make these form stainless steel, brass, or zinc alloy depending on your budget and environment—the brass ones hold up better in coastal areas with salt air, but stainless is usually fine for indoor use. Lead time is roughly 20 days or so for the 100-piece MOQ, and our company can laser engrave your logo on the clamp face if that's something you need.

One thing to keep in mind—these clamps aren't designed for sliding doors, they're strictly for fixed panels or pivot hinges, so don't try to retrofit them into a track system. flat base design gives you stable mount, but you'll want to check the screw hole alignment against your glass thickness before ordering in bulk.
We usually have stock on the chrome and brushed finishes, but matte black and golden might need a production run—confirm lead time when you're ready. Also, the 2-year manufacturing defects, not installation errors or glass breakage, which is pretty standerd for hardware like this.
Yes, we offer logo laser engraving for this model. Just send us your design file and we'll set it up for production.
Typically 10-15 working days for a standard MOQ order. Custom engraving might add a couple of days.
We can provide material test reports and a 2-year warranty certificate upon request. Just let your sales rep know.
The 50×50mm size offers slightly more holding power for heavier glass panels, but both are rated for 8-12mm tempered glass. For doors over 800mm wide, we recommend the larger size.
Keep them in a dry, room-temperature environment away from moisture. The original packaging works fine for short-term storage up to 6 months.
