The roller has an aluminum core with an M8 Allen screw and is coated with a white rubber compound of 60±5 ShA. The rubber provides excellent grip and leaves no marks on the wood.
The roller is suitable for installation in various Martin machines. We can also coat it with a different rubber compound upon request (please send us an inquiry).
Alternatively, we offer a more economical option for having the roller re-rubberized (please send us an inquiry).
