This picture frame sled will make your picture frame builds a breeze! Get perfect miters EVERY SINGLE TIME with this jig. This genius sled eliminates math when trying to determine the length because it measures from inside the rabbet. In order to make perfect picture frames you need two things… One the two corner pieces must add up to 90° and the short sides as well as the long sides must be the exact same length. This sled does it all and will save you so much time!
