I've been trying to find a mount for the Accusize display but the dovetail is larger than Brown&Sharpe or interapid. Most won't work. So I ordered this pack and it works very well. Just make sure you center the adjustment arm as it is rotated the wrong way. Good value for money. The arm goes well with our tool holders. I use the device carefully and put all the parts back in the box after each use. I have to make it last
