Our Most Popular 25mm Split Ring

This 25mm split ring is our most popular size for attaching keys, engraved tags and key fobs. Measuring approximately 1 inch in diameter, it provides more room than a compact 20mm ring while remaining suitable for everyday key management. The ring is manufactured from tempered steel and given a nickel-plated, silver-coloured finish.

Why Choose the 25mm Size?

• Popular general-purpose size: Suitable for a wide range of keys, tags and identification discs.
• Approximately 1 inch: The 25mm nominal diameter is close to one inch, making the size easier to visualise.
• Tempered-steel construction: Provides the spring action needed for a reusable split ring.
• Nickel-plated finish: Gives the steel ring a clean, silver-coloured appearance.
• Reusable attachment: Keys and tags can be added, removed or replaced when required.
• No separate connector: Items fit directly onto the coiled ring.

Typical Uses

The 25mm size is suitable for many everyday key and tag applications, including:

• Attaching engraved key tags and numbered discs
• Organising hotel, office and workplace keys
• Connecting vehicle keys to registration tags
• Fitting identification tags to locker and cabinet keys
• Creating replacement key-and-tag assemblies
• Attaching small fobs and lightweight accessories

Checking the Size

Before ordering, check that the ring will pass through the fixing hole in the intended tag. The 25mm measurement refers to the nominal outside diameter of the closed ring, so the usable internal space will be smaller.

The number and size of keys that can be fitted will vary. For an individual key or a particularly small tag, the 20mm version may provide a more compact option.

Important Information

The split ring is supplied as an attachment accessory. Keys, tags, discs and fobs are not included unless specifically stated elsewhere on the product page.

Nickel plating is a surface finish and may gradually show signs of handling, wear or exposure over time. This product is intended for general key and tag organisation and is not designed for lifting, security or load-bearing applications.
