Portals Plus 81085 Deck-mate Roof Flashing Epdm Ss Clamp

Product Description

The PORTALS PLUS 81085 is a gray EPDM deck-mate roof flashing designed to seal pipe and conduit penetrations on corrugated metal roofing. The unit includes a stainless steel clamp and accommodates projections ranging from 0.125 inches up to 26 inches in diameter, making it suitable for a wide range of penetration sizes. The aluminum flanged base is engineered to flex and conform to roof contours, irregularities, and varying pitches. Licensed roofing contractors and HVAC technicians install this flashing wherever vent pipes, conduit, or mechanical penetrations exit through corrugated metal roof panels.

This flashing is used in residential and light commercial applications on corrugated metal roofs. It is particularly well suited for HVAC flue vents, plumbing vent stacks, and electrical conduit penetrations. The DM8 size fits pipe diameters from 7 inches to 13 inches. The flexible aluminum base combined with the EPDM collar and stainless steel clamp provides a durable, weather-tight seal at the roof deck level. The unit is sealed to the roof panel using an approved sealant and standard roofing fasteners.

Compatibility

Designed for use with any configuration of corrugated metal roofing. The DM8 model fits pipe or conduit outer diameters from 7 inches to 13 inches.

Installation Notes

Installation is typically performed by licensed roofing contractors or HVAC technicians working on metal roof systems. Before installation, ensure the roof panel surface is clean and dry for proper sealant adhesion. Apply an approved roofing sealant around the base flange and secure with standard roofing fasteners per the fastener manufacturer specifications and applicable local building codes. The stainless steel clamp should be tightened evenly around the pipe or conduit to create a uniform seal against the EPDM collar.
