The Tsunami 60-day urinal screen contains 3 times more fragrance than competitors. The patented two-sided design eliminates 99% of urine splash on both sides for error-free installation. Tsunami doesn't require mounting, simply place the base over the drain and lean the body up the back of the urinal and you're done. No suctions cups to engage so it faster and there's less waste. Each screen has date tabs for replacement reminders and contain beneficial bacteria that consume odors and keep drains clean, clear, and smelling fresh.
