This 4 cm / 1.57 in spring gate O-ring is a round, openable connector for bag straps, purse chains, wallet chains, keychain assemblies and removable accessories. A spring-loaded section opens inward so compatible hardware can be added after the main product has been assembled. This makes the ring useful for detachable straps, interchangeable chains, bag charms and promotional keychain hardware that may need to be attached or replaced without rebuilding the entire connection.

Not a Lobster Clasp or Swivel Snap Hook

This product is a round spring gate ring. It is not a traditional lobster clasp, swivel lobster clasp or lever snap hook. A lobster clasp has a shaped hook body and operating lever, while this product uses an inward-opening gate built into a circular ring. Using the correct product name helps buyers compare the right type of bag and keychain hardware.

Bag Strap and Purse Chain Applications

The ring can be used as an openable connection point for handbag straps, purse chains, wallet chains, camera bag attachments, keychains and decorative hardware. Its round profile allows a compatible component to move around the ring, while the spring gate makes removal and replacement easier than with a permanently closed O-ring.

For visible hardware applications, the finish can be coordinated with the bag’s chains, hooks, rivets and buckles. Nickel works well with bright silver-tone hardware, black nickel creates a darker metal accent, and gold can complement warm-tone accessories.

Keychain and Promotional Hardware

Key tags, short chains, charms and promotional accessories can be added through the spring gate. This can simplify final assembly when branded tags or decorative pieces are installed near the end of production. The hole or chain link must be small enough to pass through the gate and large enough to move freely within the 38 mm (1.50 in) inner opening.

Wholesale Selection for Manufacturers

Bag manufacturers, leather goods workshops, keychain producers and promotional product companies should test a sample with the actual chain, strap end or connecting hardware before placing a repeat order. A large inner diameter does not guarantee that a thick chain link or metal end fitting will pass through the gate.

No verified load rating is provided. Do not use this ring for climbing, fall protection, restraint systems or any safety-critical application involving people, animals or suspended loads.

Related Bag Hardware

Explore the verified Bag Buckles, Rings and Hooks category for additional connection hardware. If this size is too large, compare the verified 3 cm spring ring. For a different profile, the 4 cm oval spring ring provides an alternative shape.

Finish and Custom Order Requests

Standard options include nickel, black nickel and gold. For another finish, a different size or a high-volume supply request, contact us with the intended application, exact measurements and required quantity. Custom requests are reviewed according to technical suitability and current production conditions.
