The Opal urinal Screen is the top of the Big D® Premier Restroom Products line, with the most fragrance and weight. THE OPAL is VOC compliant in all 50 states. It features a 1-sided anti-splash texture made of extra-long spikes that help prevent splash back and cross contamination of urine to other areas outside the restroom. THE OPAL is flexible for a proper fit to any urinal contour. The translucent design allows total viewing of the drain to ensure it remains free flowing as it collects debris before the drain is clogged. THE OPAL is also safe for use in waterless urinals. The fragrance will last for 45 to 60 days. 10 per box
