Features

Standard Ø20 mm Retaining Ring
Compatible with our SM Series of Lens Mounts and Lens Tubes
Unpackaged Weight: 0.454 g

Our SM20RR, Ø20 mm, 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.
