Diamond Series Roof Hatch

Diamond Series Roof Hatch

The new and improved Diamond™ Series Roof Hatch is designed for safe and easy roof access with higher insulation values to reduce building energy costs. The embossed counterflashing design utilizes the Diamond Grip™ to quickly secure the roof membrane and backing rod without tools or sharp edges.  The Springs are counterbalanced to comply with OSHA 1023 fall protection regulations for the single operation of latches from a ladder.  A durable factory applied powder coat finish, and corrosion-resistant hardware provides maximum protection.  The white reflective textured finish coordinates with cool roofs.
