Product details:

Single-handle, plastic bathroom faucet has a maintenance-free ceramic disc cartridge with fire-hardened discs. Low-flow aerator conserves your water supply by reducing the flow rate. 2-Hole installation. It includes a deck plate and 2 sets of mounting nuts. The black mounting nuts thread onto the shanks, whereas the gray quick-connect mounting nuts just slide right on. Depending on your preference, you could use either set of mounting nuts for installation. Using the standard NPSM inlet shanks, drop the new faucet and deck plate in place through the mounting holes of your existing faucet. Then hand-tighten the mounting nuts against the underside of the counter, and connect the hot and cold water lines.
