Product details:

This T&S B-3992-01 pull waste valve helps you avoid contact with dirty water and sharp, unseen objects by allowing you to drain and stop water from draining out of a sink without reaching your arm into the water! This unit's unique, modular design allows you to quickly and conveniently service your sink without removing the waste valve, and operation couldn't be easier! Simply pull the handle toward you to open the drain, or push it away to close the drain. An overflow assembly prevents unsanitary and dangerous overflow even if the drain is closed, while a removable snap-in strainer helps prevent your drain from becoming clogged.
