L7 Flashing™
L7 Flashing provides a high-performance solution to flashing electrical boxes, vents, and other through-wall penetrations. Pre-sized in convenient "L" shaped pieces, and fabricated from advanced butyl adhesive and coated woven facer, this unique product simplifies the flashing of electrical outlets in a cost-effective manner. Pre-cut in a standardized "L" shape, the flashing easily accommodates utility boxes of a variety of sizes.
L7 Flashing's butyl adhesive delivers rock solid adhesion at temperatures well below where other self-adhesive flashing products won't stick — while maintaining its protective properties at temperatures in excess of 225° F.
