Professionally machined out of 6061T6 Aluminum with a Type 3 hardcoat finish, these custom made diffusers provide many benefits over original L3 diffusers. Aluminum construction ensures durability for longer term use. Specifically designed to be easily repaired by the end user to be as cost effective as possible. The design utilizes two screws that hold the two halves together. The user can quickly and easily replace torn tethers, damaged halves, and diffusing sheets. A slight increase in the height of the diffuser makes it much easier to flip out of the way and place back over the aperture.
