Round Spring O-Ring
A spring-gate O-ring: 25 mm inner, 32.5 mm outer, 3.8 mm wire, with the gate cut so it opens against a strap rather than across it. Light gold and white nickel, cast body, spring tested by hand on every batch.
The gate is the first thing to fail on a cheap ring, which is why it is tested before plating. OEM Bag Hardware Manufacturer and China Bag Hardware Manufacturer terms both start at 1,000 pieces, and a China custom bag hardware manufacturer can add sizes without a new tool. Wholesale Bag Accessories buyers take these mixed with D-rings; Stamping Metal Labels, Custom Metal Nameplates and Metal Labels for Leather Goods ship alongside.
