The Chemzyme Cage E Block Maxi has been designed to be used in combination with the Chemzyme Citrus Cubes Maxi. The block fits inside the cage and the cage slots neatly onto the urinal outflow grid to provide long-lasting control of odours and help keep pipe-work clear and free-flowing. The water flush can be turned off and a once a day pouring of 5 litres of water is all that is required. Each Chemzyme Block in its cage will last approximately 6 weeks in a waterless urinal. A daily spray clean with Chemzyme fresh, a bacterial based toilet cleaner is all that is required to maintain the urinal. When the Chemzyme Block has dissolved away simply unclip the Chemzyme Cage and replace with a fresh one. These cages are perfect for use with the 80 gram Chemzyme Citrus Cubes Maxi.
