Designed for use on asphaltic systems, the M-Curb Pitch Pocket System provides a watertight seal for difficult roof penetrations and is comprised of durable M-Curb Rounds and premium-quality adhesives and sealants. M-Curb Rounds are durable curbs used to enclose the penetration by forming the pitch pocket. The rounds are bonded to the roof surface with M-Bond Sealant. The curb is then filled with a 2 (51mm) thick seal of M-Thane Two-Part Pourable Sealant (Black). M-Curb Systems are tough and waterproof, and can maintain flexibility at -40 F (-40 C) or withstand temperatures of 200 F (93 C).
