rollers that drag the boards are covered with polyurethane,
it confers and takes hold an excellent and prolonged durability.

so that it can be fit voluntarily.
This is composed of two independent groups of sandpapering,
the first group comes in contact with the board its height
is fixed with respect to the drag bench. This distance
between the roller of contact and drag can be seen in
the electronic visualizer.
The second group incorporates an adjuster that in combination
with the roller of the first group allows you to sand
a second time with sandpaper of fine degree , thus obtaining
optimal final finishing.
