Questions about this item

Should I pick the red, black or gray Neoprene insert for my NS4640DKL faucet?

All three Neoprene inserts fit the same NS4640DKL body; choose the colour that best matches your bathroom scheme.

What does the Black Onyx finish rated to ASTM B117 and ASTM B368 actually protect against?

The finish passes salt-spray testing per ASTM B117 and corrosion testing per ASTM B368, so it resists tarnish and pitting in humid bathrooms.

Will the single-hole mono-block deck plate cover a standard three-hole sink cut-out?

Yes, the included deck plate spans a 4-inch centreset layout, hiding the outer two holes for a clean single-handle look.
