Put your instrument just about anywhere
The 235-6 allows you the flexibility of having an instrument mount anywhere you want one! This adapter provides a 3½"-8 external thread as a mount for many instruments and other adapters, but also has the 2.825" - 20 internal thread required for other accessories such as a model 800 precision lift. The 235-6 is configured to mount on any flat surface, centered on a precision 3.500" bore. A mounting flange with six countersunk bolt holes is provided for secure mounting. Note that this adapter does not mount flush on a surface unless clearance is provided for the descending inner cylinder. You may also be interested in our 235-18, which has the same functionality but does not have the internal threads and does not require a hole in which to mount it, or the 5146, which does not have the flange.
