## CMM Stair Rail Calculator Description
This is a specialized app for contractors building picket-fence stair rails. The app calculates the sizes and positions of the holes to cut, as well as other useful details.

This app calculates the following information for stair rails:
- Rise
- Run
- Angle
- Rail length
- Spacing between pickets
- Number of pickets
- Spacing between holes on rail
- Height of holes on rail and on post
- Cut position and angle for cutting rail ends vertically

Convenient diagrams make it easy to enter your measurements in the app.

After doing a calculation, simply tap the Share button to share your results (via text or email), save them to a note-taking app, or copy them to the clipboard.

For many years, CMM has been a nationwide leader in industrial automation equipment for fence and rail manufacturing. Our MotionFORCE software is in use on thousands of automated routing machines across the United States and worldwide. Now, with this app, we're pleased to offer one of the features of MotionFORCE completely free!
