Bernardo Shrinker and Stretcher Foot Operated SS 18 FD – up to 1.5 mm
The Bernardo Shrinker and Stretcher Foot Operated SS 18 FD is an economical and functional piece of equipment, designed for shrinking and stretching sheet metal in workshops and on construction sites. It is ideal for working with profiles, horizontal curves, window frames, door edges, and thin sheet metal. It allows for working with steel up to 1.2 mm and aluminum up to 1.5 mm with a 25 mm throat depth. Thanks to the foot-operated system, hands remain free for correct workpiece positioning, improving precision and reducing fatigue. Supplied with two separate base bodies (shrinker and stretcher) and dedicated jaws, there is no need to change tools during work. With a weight of 29 kg and a compact structure (640 x 520 x 1300 mm), it is easy to place in the workshop and is perfect for hobbyists and professionals looking for a reliable and practical tool.

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. An essential tool for coachbuilders, boat builders, and vehicle restorers.
What sheet metal thicknesses does the Bernardo Shrinker and Stretcher Foot Operated handle?
Bernardo shrinkers/stretchers typically handle 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 for the Bernardo Shrinker and Stretcher Foot Operated. Exceeding the limits causes tool damage and irregular deformations on the workpiece.
What is the difference between lever, foot-operated, and motorized versions?
The lever (Pro) version is manual: the operator activates the lever with both hands, ideal for occasional work. The foot-operated (FD/F) version operates the machine with the foot, freeing both hands to hold and guide the workpiece—more comfortable for repetitive tasks. The motorized or electric version automates the entire cycle for series production.
Do the jaws wear out? Are spare parts available?
Yes. The jaws of shrinkers/stretchers wear out after prolonged intensive use. Original Bernardo replacement 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 effective capacity is higher than for mild steel. For specific alloys, verify thickness limits with Krollit. Customer support in Italian available.
