These industrial grade rollers are structured with a frame that comprises a centrally-located load plate and an unmoving chain of steel rolls rotating around it. The tops of the rollers are equipped with a locking mechanism to lock the swivelling, in two versions: SVD P-Rubber pad and SVD D-Diamond steel tops.
The rollers are available in the form of comprehensive sets and kits that consist of two full-sized steering handles and four rollers equipped with swivel locks.
