View attachment 1Ben R, I've used mine to rout out cutouts for commercial locks in aluminum door edges. Granted, I had to make my own accessory angles to attach to the MFS, but it really wasn't that challenging a project. I used aluminum 1x2 angle, cut down the 1" side to the height of the MFS, drilled a row of holes and bought extra MFS nuts and screws to attach to the MFS. This allowed me to clamp the jig to the edge and make it stable enough rout the 3/8 - 1/8 aluminum out. I used an Amana aluminum routing bit and copious amount of WD-40. Worse part of routing aluminum is the horrendous noise created. I would have to pay Kawneer $800.00 extra to buy the door custom prepped from factory.
