The Delta Geist 19864-BL-DST Single Handle Kitchen Pull-Down with Proclean in Matte Black performs like new for life with a patented design Delta DIAMOND Seal Technology which reduces leak points. This means less hassle to install and lasts twice as long as the industry standard. The Delta MagnaTite Docking uses a powerful integrated magnet to set your pull-down sprayer precisely into place and holds it there, so it stays docked when not in use. Kitchen sink faucets with Touch-Clean Spray Holes allow you to easily wipe away calcium and lime build-up with the touch of a finger. You can install with confidence, knowing that Delta kitchen faucets are backed by a Lifetime Limited Warranty and ADA Compliant.
