Durable and Quality! I work at a large facility that requires these types of keys to access our water points throughout the 100 acre property & buildings associated with it. The best feature is that it is light weight and fits right into your pants pocket. To add, another key feature is the key whole that is drilled into it. You can either hang it up on a key ring or add a key chain to it. The key is very handy to have readily available anytime in my tool box.
This key is small and compact enough to fit in your pocket unobtrusively, unlike the larger four-way keys that fit multiple sizes when you only need this particular one. With the small hole in the handle, it could also be placed on a key chain with other keys without any problem. It’s ideal for those restricted use faucets where there is no attached handle due to security.
