This dual gasket, flush floor cover is ideal for interior areas with more extensive movement requirements where a concealed cover is preferred. The 1/8" recessed plate accepts carpet or vinyl flooring. (Similar GTR-D and GTRW-D models feature a 3/8" recessed plate) The cover can accept lightly wheeled equipment and is good for areas where hygiene is essential. The gasket is available in four standard color options. Joint sizes range from 2" to 4". Contact the factory for larger sizes or custom applications.
