Fi Endlinks ADD-ON

Harbor Hound Co.

Size Guide


| /

These endlinks CANNOT be purchased without a HHC collar. You must purchase a Harbor Hound Co. waterproof collar that the Fi endlinks will be attached to. All orders placed without a collar will be immediately cancelled.

With our design you will be able to charge your Fi without removing the Fi Device from the collar. Simply slide the base between the Fi and the webbing and position the Fi on the base until your Fi lights up to indicate that it is charging.

Our Fi Refit is an Add-On feature that can be purchased with any 1" or 1.5" wide Harbor Hound Co. waterproof collar. Our refit design is a mounted end-link design that places the end-links permanently on top of a solid constructed collar. Our original design relieves any stress or pressure placed on the Fi device or end-links, eliminating the unpredictable and hazardous separation of the brackets on the Fi device. This will prevent an unexpected escape of your beloved pup and also the potential loss of your Fi device.

Please note a few things: Our Fi refit will take up about 6" of space on your collar and works best for collars of at least 15" or longer. Not recommended for the Peak Series collars unless the neck size/collar length is 20" or larger otherwise there may not be much room left for crystals or studs to be added. Please email me if you have a special request or question regarding the Peak Design collars. I can add the refit to Slip Collars as well but the device will be placed closer to the D-ring side of the collar so that you have full Slip capability without damaging your Fi device.
