Lockformer 20ga Pittsburgh Rollformer

The Pittsburgh Lock revolutionized the HVAC Industry in the late 1940’s and is still used today for its strength and ease in assembling ductwork. The Model 20 and Model 20 SuperSpeed Pittsburgh rollforming machines have 5 forming stations with 2 forming positions. One inboard forming position forms the Pittsburgh lock and one auxiliary or outboard forming position has the capability of forming 1 of 3 different profiles. Forming speeds are listed in the chart above. Standard with Lockformer® quality construction, these machines have motors; high precision needle-type bearings; heavy ¾” chassis plate; case hardened and ground roll shafts; and arc welded steel stands protected with Lockformer’s top-quality primer and paint finish. Alemite grease fittings are easily accessible from a central lubrication panel.

An optional Auto-Guide Power Flanger attachment is available for the Model 20 and Model 20 Super Speed Gauge Pittsburgh machines. The flanging attachment follows any edge straight or irregular while forming a 7/32 (outside) flange height. Just turn up a starting flange in the table slot, feed materials into the rolls and let go. Handles radii down to 3-1/4” or 1-3/8” manually at speeds of 16-18 fpm.
