The Kenzo Connector was created because it was the ultimate off-leash experience for a dog without really having to be "off-leash". This piece is perfect for a family of two or more dogs. The connector features two auto-locking swivel carabiners that are super light-weight, made of aviation aluminum, and most of all safe because of its auto-locking feature. The connector can also be an accessory piece that you use on your waist to connect the leash and make it "hands-free" for your hikes and runs. Please measure your waist size to see if the 3 FT or 4 FT connector will work for your size. This piece is also the perfect connector to put around a bar stool, table, and/or chair for when you're out and you want your dog to have that extra length. The connector is best used on hiking trails and other outdoors adventures!
