There are three standard diameters of pipes used in shower and floor waste drains worldwide.
They are 4 inch or 100mm, 3 inch or 80mm and 2 inch or 50mm. If you have 3 inch pipes, you will need to carefully cut the Grate Seal with a sharp blade at the point shown.
The inventors of GRATE SEAL have worked in the plumbing industry for the past twenty eight years and in that time have received numerous requests from clientele to remedy the age old problems associated with drainage outlets - smelly, offensive odours, soap suds, vermin, and noise.
It was time to address the problem so a make-shift version was created in the workshop using materials on hand.Having successfully resolved the issues and from positive feedback from an elated clientele, we then decided to design and manufacture a commercially available product now known as GRATE SEAL.
