When Do You Need Round Leather End Caps?

End caps are required in any round leather cord design where:

• The clasp attaches via a jump ring rather than a direct cord channel (as with most connector clasps, lobster clasps, and toggle clasps)
• A clean, professional cord termination is needed that prevents fraying and enhances the finish quality
• A layered or multi-strand bracelet design requires each cord to be terminated individually before joining at a connector clasp
• The design calls for an extension chain or removable pendant attachment point at the cord end

Frequently Asked Questions

How do I choose the right end cap size for my round leather cord?
The inner bore of the end cap must match the outer diameter of your round leather cord as closely as possible. A 3mm cord needs a 3mm inner bore end cap. Too loose and the adhesive joint will flex and fail; too tight and the cord will not seat properly. If unsure, contact us with your cord diameter and we will recommend the right product.

Do I always need end caps when finishing a round leather bracelet?
Not always. Our magnetic clasps for round leather have a built-in internal channel — the cord inserts directly and is glued in place, so no separate end cap is needed. End caps are required when attaching a clasp that connects via a jump ring — such as a lobster clasp, toggle, or hook style from our connector clasps for round leather range.

What adhesive should I use with round leather end caps?
Use a strong jewellery adhesive rated for bonding metal to leather. Apply a thin, even coat to the inner walls of the end cap, insert the cord end until fully flush, hold for 30 seconds, and allow 24 to 48 hours of full curing time. See How to Finish Leather Cord Jewelry Ends Professionally for detailed technique guidance.

Can I use round leather end caps on braided leather cord?
Yes, though braided leather cord is slightly bulkier than standard round cord. Size up by 0.5–1mm on the end cap bore to account for the braid. Test with a small order before committing to bulk quantities.

What is the difference between "End with Loops" and "Round End" types?
"End with Loops" caps have an integrated loop at the end, used to connect a jump ring, extension chain, or secondary clasp. "Round End" caps have a smooth domed finish with no loop — used in designs where the cord end itself is the final visual element with no additional connection needed.

Why are some end caps priced by weight (100g) rather than per piece?
Some zamak end caps in the range are sold by weight rather than individually. The approximate piece count per 100g is listed on the product page where available. This pricing format is common for smaller zamak components sold in high volume. If you need a specific piece count, contact us before ordering.
