Description & Size guide

We decided to stock this handy biner initially as an accessory for the H204K9 bottle and K9Unit bottle, in order to keep your and your dog’s water steady and safe no matter how long you hike. It will free up your hands throughout your trails or runs.

It will certainly come in handy for other things too such as attaching equipment to yourself during dog training sessions or even adding an extra loop to your dog leash for tethering when out in the hills. For a small, and simple, invention the Nite Ize S Biner is a fantastic addition to your outdoor kit. The black steel, weather resistant double clipping carabiner is an item that you will wish you have found sooner.

No more tying up fiddly strapping, or stuffing dog leashes into pockets, because you have no way to secure them to your pack. This simple use S shaped double steel gadget will take up, and hold firmly, the slack however you choose to use it. Strong and sturdy with sprung clips the Nite Ize S Biner Steel will soon become invaluable. We fully expect you to come back for more.
