Why You’ll Love It: A cylinder arm machine is great until you are trying to sew a flat panel and the work keeps rolling off the arm. This platform drops over the arm and gives you a flat table to work on, then lifts off in a second when you need the cylinder back. It is the accessory most people buy after fighting a wallet interior for an hour. Key Specs: Fits: Cobra Class 26, Class 3 and Class 4 Type: Removable flat bed attachment Install: Drops on and lifts off, no tools Things to Know Before You Buy: Pick your machine from the dropdown. These are not interchangeable between models Class 26 and Class 3 or 4 platforms are different parts at different prices If you are not sure which machine you have, check the badge on the head before ordering Best For: Flat work like wallet interiors, panels and linings Long straight runs where you want the work supported on both sides of the needle Anybody who does more flat sewing than round sewing More About This Product: A cylinder arm is the right choice for bags, sheaths and anything you sew in the round. The trade-off is that flat work gets awkward. This platform gives you both machines in one. Leave it on for a batch of wallets, pull it off when a bag comes across the bench.
