Explaination: When ordering a 3 post rail with the base plate or for use as the core drill method post placement is critical. In most cases you want all three posts to be the same height and each post placed the same distance from the nose of the step—about 4 inches. This will insure that your rail meets the pitch of your steps with out drooping or rising at the mid post.

Record your measurements. This will help us make your rail to fit your steps.
Using the diagram below record the two nose to nose measurements. The picture below has 7 treads because the landing at the top is not counted. If you have an even number of steps like 4 or 6 the two nose to nose will be nearly equal.
How many treads/steps do you have? _______
What is your overall nose to nose? ________
What is your mid post nose to nose? ___________
With an odd number of treads there is no true center. Choose one of the two most center steps. The options are shown as dotted line posts.
