Baader's New VariLock T-2 Extension Tubes give you complete adjustability to enable you to exactly set or vary the spacing between T-2 components. Perfect for exact positioning of reducers, coma correctors, and other optical or imaging system components.

The VariLock extension tubes feature an accurately engraved graduated scale for an easy visual determination of the tube length (0.5mm graduations). Simply rotate the inner tube until the desired length is reached, then tighten the lockring with the included spanner wrench.

Full internal threading and blackening kills any stray light reflections. 2" OD enables use in any 2" system.

The Varilock 46 is also perfectly suited for setting the correct spacing of the new Baader RCC-I coma corrector onto DSLRs (when adjusted to 36.5mm).

As an added bonus, the external T-threaded portion can be removed and replaced with a dovetail ring (included) that inserts into standard camera T-rings, for use with DSLRs.
