Bought for my father. We're always building something here. This month's project is a 20x40 extension to his home. The wooden magnet is made to be suitable for double material. Beams - check bolts - check traverses - check. The wood magnet also has a rubber band that isn't as well seen on the web that can be attached to any other alignment material like a 4x4 or metal bar. I would definitely recommend this article if you are looking for a level well done.
