GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
