We usually quote roughly 288 hinges per carton, give or take, which covers about 36 door sets or so — check your door count before ordering because lead time can vary (usually 2-4 weeks on bulk orders).
What it solves basically is doors staying open in public restrooms, which kills privacy and lets smells escape, and we've seen it cause a lot of complaints in high-traffic setups.
The thickened self-returning spring does the work, it's pretty aggressive about closing the door all the way without slamming, and the 180° opening angle helps with wheelchair access or mopping floors — not ideal for solid wood doors over 50kg though, alumnum alloy is better for lighter panels.
Surfce mount instalation is straightforward, but most buyers don't realize you need a 3mm gap for the hinge to swing fully, and corrosion-wise the oxidation finish handles humidity fine for years without rusting.
Bulk carton packaing means they come stacked tightly, maybe 48 per box inside the carton, and we include COAs with HPLC data on alloy composition per batch but not on every hinge obviously.
Anyway, one thing I always mention: the spring tension is usually set at the factory for standdard restroom doors, so if you're mounting on a heavy fire-rated door or an exterior one, it might not close reliably without upgrading the spring.
Yes, it's rated for up to 50kg, so a standard solid-core door won't be a problem. The thickened self-returning spring is designed to handle that weight reliably.
Absolutely. The oxidation finish gives it high corrosion resistance, so it holds up really well in damp environments like public restrooms or shower facilities.
We typically ship bulk carton orders within 7-15 days. The MOQ is usually 100 pieces, but we can discuss smaller quantities depending on stock.
It's a surface mount hinge, and the package includes standard mounting screws. If you need longer or corrosion-resistant screws for special conditions, just let us know.
Yes, we can supply a test report for the aluminum alloy and oxidation finish. Just request it with your order, and we'll include it in the shipment.
