"For custom configurations performed on-site, the MD Ramp System is made of 100% nitrile rubber, and fit the male/female locking system of the mat. All ramp lengths are beveled and molded with mitered corners and a protruding tab that locks together the two adjoining ramps for a secure, professional corner. Square edges can be achieved by trimming off the miter using the cut line on the bottom of the ramp."^^<http://www.w3.org/2001/XMLSchema#string>
