Aztec Washer Company, #SQ301BA Master Flash Square Flashing - (1/4 in. - 5 3/4 in.)

This standard roof flashing's flexible design meets virtually all roofing needs. Made of EPDM, the flashings are compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light. Easy on-site customization allows for easy installation in usually five minutes, and the flexible soft aluminum base is designed to form a seal on most panel configurations and roof pitches regardless of pipe location.

Select the appropriate Master Flash for pipe or duct diameter. For extreme pitch or surface irregularity select next larger size.
