25 mm / 0.98 in Fixed Spring-Loaded Keychain Ring with 12 mm / 0.47 in Lower Opening SB 8975

This fixed spring-loaded keychain ring is designed for bag makers, belt manufacturers, leather-goods workshops, keychain producers and accessory designers. Its main spring-loaded ring and separate lower opening provide two connection areas within one zinc alloy body.

How Is the Ring Used?

The spring-loaded main section allows a compatible chain link, ring or accessory component to be attached and removed. The 12 mm / 0.47 in lower inner opening provides a fixed connection area for compatible straps, webbing, cords or connecting fittings.

Verified Measurements

• Main inner dimension: 25 mm / 0.98 in
• Lower inner opening: 12 mm / 0.47 in
• Outer dimension: 35 mm / 1.38 in
• Body thickness: 4.6 mm / 0.18 in

Compatibility Check

Do not select the ring by nominal width alone. Measure the width and thickness of the strap, webbing or cord that will use the lower opening. Also check whether the chain link or connecting component can pass through the spring-loaded section without forcing it.

Sample testing with the actual connecting parts is recommended before bulk manufacturing.

Applications

The ring can be considered for bags, wallets, belts, keychains, camera bags, short straps, decorative chains, compatible pet accessories, camping products and textile-accessory systems.

Fixed Spring Ring or Standard Round Spring Ring?

A standard round spring ring is suitable when only one openable connection area is required. This fixed model is more appropriate when the design also requires a separate lower attachment point for a strap, webbing or connecting component.

Material and Finishes

The body is made from zinc alloy, also known as zamak. Nickel, black nickel and gold finish options are listed. Match the finish with visible hooks, buckles, chains and rivets used on the same product.

Important Limitation

No certified working-load or safety-load rating is stated. Do not assume that the ring is suitable for climbing, lifting, life-safety or certified load-bearing applications.
