Review on Heavy Duty XINDA Screwgate Locking Carabiner Clip For Rock Climbing, Mountaineering, Hammock & Camping Outdoor Equipment by Cedrick Ayudara

I use these for my dogs. I have one carabiner attached to the handle of each of their leashes and then just hook them together or release them as needed. Very handy to only have to hold one leash. I also keep one attached to the back seat belt. Open door, hook leash carabiner to seat belt carabiner, and now my hands are free to pick them up and put them in the vehicle without worrying about one of them wandering off on an adventure. Reverse procedure for exiting the vehicle.
