TUFTEX® Universal Ridge™ was developed to be used with both TUFTEX® PolyCarb™ panels and TUFTEX® Multi-Wall™ panels. Because projects and structures can vary greatly in design and slope, the Universal Ridge can be trimmed along the sides to create the perfect width for your project. Fastening guidelines are shown as minimums or maximums to allow you to fasten the ridge according to your project specifications.
