*Clearance* Portals Plus Premolded Corners - 52020, 51030, 52030

The Portals Plus Premolded Corners (items 52020, 51030 & 52030) provide pre-fabricated inside and outside corner flashings designed for parapet walls, mechanical openings, skylights, roof-top furnaces and other roof interface points. Each unit is injection-molded of 0.060″ thick EPDM (for single-ply membranes) or Neoprene (for built-up roofs) and features 8″ height with 6″ legs, radius corners, and feathered edges to optimize adhesion. The corners are ozone and ultraviolet light resistant, and offer a service temperature range from –60 °F to +270 °F.

Key features:

• Pre-molded inside and outside corner flashing eliminates cutting and folding of sheet materials. 
• Injection-molded 0.060″ thick EPDM or Neoprene for durability in single-ply or built-up systems. 
• 8″ height with 6″ legs, radius corners and feathered edges for excellent adhesive bond. 
• Service temperature range from –60 °F to +270 °F, ozone and UV resistant. 
• Compatible with roof systems that use or do not use built-in cant strips
