Let Versico simplify your next VersiWeld TPO installation with pre-punched T-Joint Covers. VersiWeld TPO T-Joint Covers are used to seal step-offs at splice intersections. T-Joint Covers are mandatory on all 60- and 80-mil TPO systems and on 45-mil systems where step-offs have not been properly sealed. VersiWeld TPO T-Joint Covers consist of 60-mil non-reinforced flashing punched into a perfect 4.5"-diameter circle and packaged 100 parts per carton. Available in white, tan and gray. Versico’s VersiWeld TPO T-Joint Covers are part of the Certified Fabricated Accessory (CFA) Program. Certified Fabricated Accessories are the only factory-fabricated accessories that meet the stringent quality tolerances required to be included in a Versico warranted roofing system
