Portals Plus Deck-Mate Gray EPDM w/ Clamp

Deck-Mate is a molded gray EPDM roof flashing for metal roof and wall systems. Its stepped profile creates a compression seal around Schedule 40 piping, while reinforcing ribs help the boot maintain shape under clamp pressure. A dead soft aluminum flange bends to match roof contours and pitches for a tight fit. The assembly uses a stainless steel clamp to maintain a long-term, watertight seal without relying on caulk.

Key features:

• Stepped EPDM profile forms a compression seal around Schedule 40 piping.
• Reinforcing ribs maintain rigidity and shape under clamp loading.
• Dead soft aluminum flange conforms to roof contours, irregularities, and pitch.
• Stainless steel clamp provides durable, watertight sealing without caulk.

Q: What penetration range do Deck-Mate flashings cover?
A: The series accommodates approximately 1/8″ up to 26″, depending on the selected DM size.

Q: Why is a clamp used instead of caulk for sealing?
A: The clamp maintains a long-term compression seal; caulk is not recommended as a primary sealer for penetrations.

Q: Will Deck-Mate conform to uneven or pitched metal roofs?
A: Yes. The dead soft aluminum flange bends to match contours, irregularities, and roof pitch.

Q: What material and temperature performance does the boot provide?
A: It uses gray EPDM rubber serviceable from −60°F to +270°F and designed for outdoor exposure.
