The BSC PREFERRED LK105CR is a chrome air gap designed for residential kitchen and bathroom sink installations. An air gap is a critical backflow-prevention device that physically separates the dishwasher drain line from the sink drain, protecting the potable water supply from contamination. The LK105CR features a corrosion-resistant chrome finish and compact dimensions of 2.125 inches tall by 1.75 inches wide, keeping the deck footprint minimal. It ships ready to install and is suited for licensed plumbers and skilled DIYers performing faucet deck work or dishwasher drain hookups.
The LK105CR is appropriate for standard kitchen sink installations where local plumbing codes require a physical air gap on the dishwasher drain line. It fits into a standard faucet deck knockout or pre-drilled hole on a kitchen sink. The chrome finish coordinates with common faucet finishes in both residential and light-commercial settings. No special tools are required beyond standard basin wrench access for under-deck securing.
Designed as an OEM-style replacement or new-install air gap fitting for standard residential kitchen sink faucet decks with a pre-drilled or knockout hole sized for deck-mount accessories.
Installation is performed by a licensed plumber or qualified installer in jurisdictions where local code requires a permitted plumbing rough-in. Shut off the dishwasher and disconnect power before working on drain line connections. Hand-tighten the mounting nut from below the deck to avoid cracking the sink surface, then snug with a basin wrench only. Verify local IPC or applicable plumbing code requirements for air gap placement and drain line routing before completing the install.
