The Red Shark is the most aggressive pad holder in the range. Good resistance to heavier chemicals but can be aggressive to softer pads and melamine.
Before inserting the Excentr Red Shark, it is very important that the aluminium pad holder is clean and free of grease.
TIP: Use a high-pressure cleaner to remove glue residue etc. from the aluminium pad holder, and a strong degreaser for degreasing.
