William Optics RotoLock Visual Back Adapters

William Optics RotoLock adapters are visual backs that hold a diagonal or eyepiece with a rotating clamp ring, which centers it and lets you turn it without loosening the connection.

The range includes 1.25" and 2" adapters for SCT threads, a 2" RotoLock Adapter SCT 3.28" for larger thread sizes, a 2" RotoLock for M63 focusers, a 2"-1.25" reducer and a 3.5"-2" adapter for large focusers. They suit refractor and SCT owners who want a secure, centered visual back.
