Cutting Mitered Pieces into Equal Lengths

Is there some kind of jig or procedure to help me cut mitered pieces into equal lengths?

Michael Dresdner: Yes, and as luck would have it, we covered it here in Issue 158 of the Woodworker’s Journal eZine. It is a clever jig made by Kreg called the Perfect Miter Attachment that allows you to accurately reproduce mitered lengths with the point on either the far or near side of the miter fence.
