Bernardo Lever Shrinker and Stretcher SS 150 Pro
The Bernardo Lever Shrinker and Stretcher SS 150 Pro is a professional manual machine for shrinking and stretching sheet metal, designed for precision and robustness. It can work steel up to 1.5 mm and aluminum up to 1.8 mm, with a throat depth of 150 mm, ideal for medium-sized panels and profiles. Supplied with two separate attachments (one for shrinking and one for stretching), it eliminates the need for tool changes, speeding up processing. The long lever ensures greater force and control, reducing operator effort. With a weight of 34 kg and a robust structure, it is stable during use, but still easily transportable in the workshop or on site. A versatile tool for body shops, restorers, and professionals who need accurate, wrinkle-free results.

Frequently asked questions
What does a shrinker do and what does a stretcher do?
The shrinker compresses the metal fiber at the edge, shortening it and creating a concave curve. The stretcher elongates the fiber by expanding it, creating a convex curve. By alternating the two functions, complex shapes can be achieved on thin sheet metal without wrinkles or tears. Essential tool for body shops, boat builders, and vehicle restorers.
What sheet metal thicknesses does the Bernardo Lever Shrinker and Stretcher work?
Bernardo shrinkers/stretchers typically work steel up to 1.2–2.0 mm and aluminum up to 1.5–2.5 mm depending on the model. Check the specific limits in the technical table of the Bernardo Lever Shrinker and Stretcher. Exceeding the limits causes damage to tools and irregular deformations on the workpiece.
What is the difference between lever, foot pedal, and motorized versions?
The lever version (Pro) is manual: the operator operates the lever with both hands, ideal for occasional work. The foot pedal version (FD/F) operates the machine with the foot, freeing both hands to hold and guide the workpiece — more convenient for repetitive work. The motorized or electric version automates the entire cycle for series production.
Do the jaws wear out? Are spare parts available?
Yes. Shrinker/stretcher jaws wear out after prolonged intensive use. Original Bernardo spare jaws are available with 3–5 business day shipping. Replacement does not require special tools.
Does it also work on copper and brass?
Yes. Copper and brass are more ductile materials than steel: the actual capacity is higher than for mild steel. For specific alloys, check thickness limits with Krollit. Customer service in Italian available.
