Variable Neutral Density Filter Mount for Round Neutral Density Filters

M6 threaded hole on the main body, with M4 threaded hole adapter included
Compatible with NDFR series filters with center hole diameter Ø7.5 mm
Suitable for optical elements with a thickness of 2 mm

The LBTEK Neutral Density Filter Mount allows the installation of NDFR series filters with a central hole diameter of Ø7.5 mm onto the rotating shaft. To install the filter, first use the included 1.5 mm hex wrench to tighten the fixing screw on the side of the NDFR-PM to lock the rotation. Then, use the included 2 mm hex wrench to remove the silver hex socket screw. Place the filter between the two washers, then reassemble the rotating wheel and screw combination. Please note to maintain the original sequence of flat washers and wave springs when reassembling, and securely fasten the bolt. The package includes one each of 1.5 mm and 2.0 mm hex wrenches.
