The Elzetta ZFH1500 is made from a glass-filled polymer, providing outstanding durability, impact resistance, scratch resistance, and light weight. It also withstands high temperatures, vibration, and most chemicals. The Elzetta ZFH1500 comes with Sizing Adapters, giving the Flashlight Holder the ability to mount flashlights from 0.7 to 1.1 inches in diameter (18 to 27 mm). This includes such popular flashlights as the Mini-MagLite®, PentagonLight®, Inova®, Streamlight®, Pelican®, Laser Devices®, and many SureFire® models. The version that we carry has a Quick-Release Thumbscrew, which allows flashlights to be installed and removed rapidly and without tools. It also provides a more robust clamping mechanism while retaining the nut on the device. The Thumb Screw Model is highly recommended. *Flashlight Not Included. All Elzetta products are Made in the USA.
