The Ratchet Bracket System is the newest and most versatile system out there today making under mount sink installation simple and quick. The Ratchet Bracket attaches easily to either the front or sides of the cabinet wall. PSA tape temporarily holds it in place and two screws secure it. Simply peel the backing off of the PSA tape, press the bracket against the cabinet wall, and screw the bracket into place. After effortlessly screwing the track to the cabinet walls, push up on the sink and the job is done! It makes sink installation so quick and simple! There are two models to choose from—short arm and long arm. The short arm is for front sink support, tight situations, and composite sinks. The long arm is for standard or large cabinet bases. A repair clip is also available to easily repair any fallen front sink.
