Yes! Our BioThane® accessories are made with solid brass or Sport (carabiners made from aircraft grade aluminum paired with and black steel) hardware. All are water proof, odor proof, and easy to clean.
Most accessories clip to a leash D‑ring or can be attached via a carabiner to our Utility Belt or your own waist belt. Some items (like leash keepers or traffic handles) are intended for specific products; see each product page for instructions.
Soak in warm soapy water, clean with a towel or sponge, and rinse with water. For tough messes, a light scrub with a soft sponge or toothbrush works well. Always store dry. Solid brass will not rust, but may develop a natural patina over time. Black‑coated hardware may show cosmetic wear or rust over time, but strength isn’t compromised.

When purchasing my first 50ft long line I saw the option for a long line keeper and figured at the least it would be helpful for storing the line, however after working with the line a bit I found so much use for the line keeper other than storage. From securing the line when I had it wrapped around my waist to keeping the extra length picked up, it has been a godsend. Not to mention the color description was perfect and I was able to find the same exact color of biothane for the line keeper as my service dog’s main working harness, leash, and collar.
Thank you so much, Elyot! We’re thrilled to hear the long line keeper has been such a game changer for you — it’s amazing how versatile that little piece can be! We love that it’s helping with everything from storage to managing extra length on the go.
And matching your service dog’s full setup? That’s next-level — we’re so glad the color was spot on! (Thanks for sharing pics too!) Wishing you and your SD many smooth, organized, and stylish adventures ahead. ✨
After having multiple long lines for my dog, it quickly became apparent that I needed some organization for them.
I purchased one of these BioThane Quick Release Long Line Keepers to take it for a test drive. I like adjustability of the holder. It slides to accommodate my 12' as well as my 30' leashes. It also clipped on my pack nicely. It was easy to clip and unclip from my backpack and belt.
I ended up ordering two more of these for all of my long lines. Now I keep them all organized and very accessible with these Keepers. Highly recommended!!
Wow, Thank you Toni! Doesn't it feel good to have everything organizing and easy to get to! So glad you are enjoying your HTH gear!
