Gutters that use the T-Rex® system are closed and seamless. Unlike gutters installed with nails, hooks or brackets, which are left open and exposed, gutters equipped with T-Rex® continuous hangers™ are solid and protected from leaves, debris, snow, and ice. In addition to requiring much less maintenance, your gutters will flow smoothly year-round, ensuring that water doesn’t get under the roof or too close to your home’s foundation.
