Our new M2 model is here and we've added a special touch to it. The new Massca M2 Aluminum Pocket-Hole Jig Pro comes with steel stabilizing bars and stop blocks. Our M2 Pro Jig is making it easier than ever to work with longer pieces of lumber and repeat measurements. Each model comes with two lockable steel bars and support stop blocks that adjust laterally to the exact width of your desired measurement to now provide more stability and versatility to your pocket-hole cut.
