Wayne, NJ – March 4, 2026 – Haydon Corporation, a U.S.-owned, U.S.-based national manufacturer of high-performance metal framing and rooftop support systems, has announced the expansion of its high-visibility end cap design to the H-BLOCK® Mini and Mega Rooftop Support products.
Following the successful transition of H-BLOCK® Standard supports to the new high-visibility cap design in 2025, Haydon is extending the same enhancement across its Mini and Mega product lines, creating a unified, jobsite-ready rooftop support portfolio.
The high-visibility end caps improve rooftop visibility while maintaining the same trusted performance, material specifications, and load ratings contractors rely on. Mini and Mega supports continue to be manufactured in the USA using 100% recycled rubber and remain compatible with existing infrastructure installations.
“Consistency across the product line matters to our partners,” said Kate Schuster, Vice President, Commercial at Haydon. “By extending the high-visibility cap design to Mini and Mega blocks, we’re reinforcing our commitment to jobsite safety, performance reliability, and continuous improvement without disrupting the specs our customers depend on. At the end of the day, these enhancements are about making work on the roof safer, faster, and more predictable for the crews who rely on our products every day.”
H-BLOCK® Mini supports provide up to 400 lb. uniform load capacity, while H-BLOCK® Mega supports offer up to 7,500 lb. uniform load capacity, delivering durable, stable rooftop support solutions for HVAC, conduit, pipe, cable tray, and solar applications. The enhanced H-BLOCK® Mini products are expected to begin shipping in March 2026, with Mega products following in May 2026, as existing inventory transitions.
Haydon’s H-BLOCK® Rooftop Support Systems are:
- Made in the USA with 100% recycled, domestically sourced rubber
- Pre-assembled for fast installation with no roof penetration required
- Tested for extreme environments, including UV resistance and freeze/thaw performance to -40°C
- Membrane safe and compatible with most rooftop materials
- Designed to support HVAC systems, ductwork, conduit, pipe, solar racking, and more
The enhanced H-BLOCK® line complies with the Buy American Act, Build America, Buy America Act, American Reinvestment Recovery Act, and is LEED certifiable.
