Our SM05RR, Ø1/2", Standard Retaining Ring is compatible with our extensive line of SM Series lens tubes and mounts. Securing an optic using a retaining ring is probably the most stable method for holding the optic since the optic is retained along its entire edge, not just at a few points. The retaining ring is thin so that the clear aperture of the optic is only minimally affected.
