Quick-install assembly for a single control faucet

A quick-install assembly for a single control faucet connected to water supply lines that extend through an opening in a deck to which the faucet is mounted, which assembly has a collar of larger diameter than the diameter of the opening of the deck and positioned from above the deck to be disposed at the opening of the deck. The collar has a pair of ears formed thereon that extend over the opening in the deck. A pair of fasteners are operatively engaged from above the deck to be threadedly connected to the ears to be disposed from above through the opening of the deck. A retainer is threadedly connected to the fasteners and includes a pair of swing flaps thereon adapted to be axially shifted toward and away from the collar responsive to the direction of rotation of the fasteners. The pair of swing flaps rotate on the fasteners between a closed position that provides a small dimension that passes through the opening of the deck and an open position that provides a long dimension with each swing flap pivoted outwardly so that when the retainer is disposed below the deck and the retainer is shifted upwardly each of the swing flaps will clamp against the underside of the deck to clamp the quick-install assembly thereto. Lastly, connecting device are operable from above the deck to connect the faucet to the collar whereby the faucet will be mounted upon the deck.
