Retrofit Masterflash®-Square Base Retrofit Flashing
- The Retrofit Masterflash® is a simple solution to flashing a penetration through a metal roof that requires a wrap-around installation. The Retrofit Masterflash® easily wraps around existing or hard to reach penetrations. The clearly marked diameters on each flashing allow the Retrofit Masterflash® to accommodate a range of sizes. The marked dimensions also allow for easy sizing to fit each individual application.
- The Retrofit Masterflash® makes installation simple by using easily installed snap rivets. A cable tie is also supplied to reinforce the seal.
- Available in black EPDM or orange silicone, both flexible materials, the Retrofit Masterflash® is resistant to ultraviolet rays, cracking & weathering.
- The aluminum base on the upper lip of the Retrofit Masterflash® is corrosion resistant and allows the flashing to conform to any panel configuration and/or roof pitch.
