Spanner Wrench, 30 mm LT Series Lens Tubes

The LT30M-WR retaining ring wrench is used for LT30M-RR, 30 mm retaining ring installation and removal. This tool is made with an extended lip to help hold the retaining ring in place and has a hollow body so as not to obstruct the beam path during installation and adjustment.  The inner diameter of the wrench is extra large to accomodate fast lenses with large curvatures.  These wrenches are also made for 0.5", 1", 1.5", 2" and 3" LT series retaining rings.
