This is a ø10mm rod, on which 2 rows of rubber fingers are vulcanized in a U shape. Compared to the V10 profile, the rubber fingers are vulcanized to the sides of the rod instead of on the top. These fingers are approximately 25mm high and asymmetrically placed, also 20mm from each other. A U-profile hedgehog web has the advantage of having sieve capacity. This profile is not available in every width.
