Chant Engineering is the authorized North American distributor for Friedrich Hoeppe thimbles. We carry in stock the solid DIN 3091 Thimbles painted black to minimize rust. These high quality thimbles have been made by Friedrich Hoeppe in Germany for over 100 years.
The thimbles according to DIN 3091 are cast from GGG 40, not machined from a solid piece of steel. Custom hole sizing is available upon request.
