The continuous version of the sawtooth support is where the sawtooth cut runs the entire length on the support. This style allows several lengths to be joined for use in taller cabinets. It also can be used as a center section by adding a plain support piece on either end extending the length at a lower cost. The cleat material included with each set is the same dimensions as the supports so can be used for the extensions.
4 Stars Nicely made

Nicely made, easy to install. One bit of advice: the shelf notching template assumes your shelves extend from back edge of rear standard to front edge of front standard. If your shelves are set back a bit from the front edge, you'll need to cut a smaller notch.
