Finish-Matched Upgrade
Matte Black (finish code MBL) coordinates with today’s black faucets and accessories for a cohesive suite. Swapping the lever preserves the original Nexus styling while updating the finish to match the rest of the room.
Verified Nexus Compatibility
This is the exact lever TOTO specifies for the Nexus line—including CST642CEFAT40 and CST642CEFGAT40 two-piece packages and MS642 one-piece variants—so handle travel and linkage geometry align with the factory flush assembly.
Fast, Front-Side Installation
Designed as a direct replacement, the lever installs from the tank exterior with basic hand tools—no bowl removal, no reset of internal valve settings, and minimal downtime for the bath.
Reliable Everyday Operation
Using the genuine lever maintains the intended feel and return action of the Nexus flush mechanism, helping avoid sticky or short-stroke flushes that can happen with off-spec aftermarket parts.
Durable, Easy-Care Surface
The factory Matte Black finish is engineered for everyday cleaning and consistent appearance over time. Wipe with a soft, damp cloth—no abrasive pads— to keep it looking new.
