Increase the flexibility of your SnakeClamp with our 5" (127mm) diameter 3x magnifying glass. The visible area of the lens is reduced to approximately 4.6" (118mm) diameter due to the width of the magnifier frame. The glass lens is colorless. See our Magnifying Glass Collection for other lens options. This product does not include an optional handle since it is intended for use with a flexible gooseneck arm, but one can be purchased separately. Frame is made of strong glass fiber reinforced nylon. 3/8"-24 threaded stud for attaching to SnakeClamp brand flexible gooseneck tube arm. Assembled in the USA with foreign components. Weight: 14.4 ounces.
