This is the portion of the flashlight strap that stays on the firefighter's belt. If you are purchasing flashlight straps for your entire department, you likely need more of the straps that stay on the firefighter's belt than the flashlight portion of the strap. You can purchase the same amount of flashlight straps (FFFS) as you have flashlights and additional belt portions of the strap so every firefighter can keep it on their belt.
