Hello Ann Randolph,
Thank you for your question. The "BLSD" lettering of the Delta Everly ShieldSpray Pull-Down Kitchen 19741Z-BLSD-DST faucet, stands for the finish color Matte Black (BL) and the soap dispenser (SD). This faucet also has an optional escutcheon plate included for use with additional mounting configurations and a cohesive look.
