Install a Stabilization Plate for Thin Sink Decks

1. Shut off the water supply lines under the sink to prevent accidental leaks during hardware removal. 2. Loosen and remove the existing mounting nut and hardware from the faucet's threaded shank. 3. Insert a metal stabilization plate between the sink basin underside and the mounting bracket to provide a rigid surface. 4. Reinstall the mounting nut and tighten it clockwise with a basin wrench until firm. 5. Turn the water supply back on and check for stability by operating the faucet handle, ensuring the base remains stationary.
