Put an instrument mount anywhere!

The 235-18 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. The 235-18 is configured to mount on any flat surface. A flange with six countersunk bolt holes is provided for secure mounting. You may also be interested in our 5146, which does not have the flange, or the 235-6, which has the same functionality but also has internal threads to accommodate other products such as our model 800 precision lift.
Be sure to have a look at all of our instrument adapters for 3D or alignment instruments.
