Choose a machine based on your required profiles. One machine can form one or multiple lock profiles.

Forms Pittsburgh lock seams for rectangular HVAC duct panels. Additional edge profiles depend on the selected roller tooling.

Forms S-lock and matching cleat profiles for sheet-metal duct connections. Available shapes depend on the machine model and roller set.

Forms snap-lock edges for compatible sheet-metal corner connections. SNAP model: 0.4–1.0 mm sheet thickness.

Forms conventional and snap-lock seams for curved HVAC duct elbows. Guided feeding reduces the need for continuous hand-holding. LA-15: 0.5–1.5 mm sheet thickness.
