Fast Flash is a self adhesive lead replacement material that has many uses beyond replacement for traditional lead. Fast Flash can be used to flash large round or square penetrations that a Dektite cannot cover - with its self adhesive backing you'll have a water tight penetration in minutes! 

This part can be used on GSE In-Roof or Easy Roof In Roof systems as a sealing strip replacement.

It can be used to provide a continuous waterproof border along the bottom edge of the PV array. It can also be used for the bottom edge of the array instead of lower metal flashing components
