Eco-Fresh Non-Para Enzymatic Block and Screen, Green Apple Scent, White, Dozen

Enzymatic Block and Screen protects urinal drains from debris which can result in costly repairs. The screen contains a 2.8 oz block that deodorizes consistently for up to 1,200 flushes. The billions of bio active enzymes consume odors at the source for a true clean. After 1,200 flushes the block can be replaced and the screen reused so there is less waste.
