A very sturdy accessory to the DW715 saw. I bought one, and was installing it on the left side of the blade (as this is where I do most of the cuts), and noticed the saw would accommodate one on the right side. So I immediately bought another! Very well constructed, comes with all the necessary parts, and room is allowed on the upright supports through slotted holes to adjust the height to be level with the bed of the saw. Something not discussed in the assembly instructions is the fact that two or more of these could be joined together via threaded holes in the extension rods. This will be extremely useful for supporting crown molding.  A great product!
