In particular, the bottom sliding profile is only 2.1 cm in height and the tracks are coated in stainless steel to ensure extended duration and lasting operability. The wheels of the sliding trolleys are in stainless steel, 2.8 cm in diameter with shielded ball bearings. Handles and knobs are round-shaped and completely in stainless steel, as are the locking systems, available as manual or with key.
