Otis Gen2 Scratch !!install!! -

These belts are thinner and more flexible, allowing for a smaller, gearless machine that doesn't require a machine room (MRL). The "Scratch" Issue:

The Gen2 uses coated steel belts (12.5mm or 25mm wide). If the belts are not perfectly centered on the traction sheave or the diverter pulleys, the steel edges can shear against the polyurethane coating or the metal guards. otis gen2 scratch
