The Gutter Runner automatic crimping tool attaches to most gutter machines, including KWM Gutterman machines, and creates small notches on the back of the eavestrough every 6”. This allows the T-Rex continuous hanger gutter guard to snap into place, fitting snugly on the eavestrough. The automatic crimping tool can also be adjusted when not being used. This week enjoy a FREE Gutter Runner when you purchase 5 cartons of T-Rex 5200 continuous hanger system. 🎉 Valid until Friday, April 10th, 2020.
