The Lockformer Duct Spin Collar Maker Machine allows you to make your own spin collars in minutes. Just cut galvanized stock (24 gauge and lighter) to width and length, set the diameter from 4" to 16", and push the blank against the automatic stop. A synchronized die notches the lead edge for easy spin-installation on the job site. The notched piece is then pushed past the stop, feeding the part into the roll former and finally into the automatic crimping and curling operations. Two models are available:Model 6: 2" to 6" wide collarsModel 12: 2" to 12" wide collars
