About this item
The RD is the structural screw that finishes the IronRidge HUG attachment. A #14 self-drilling wood-tip screw in 300-series stainless steel with a clear finish, 3" long, with a 5/16" head and an EPDM-backed sealing washer pre-loaded under the head.
Self-drilling means no pilot hole on most rafters. The stainless body resists corrosion in coastal and high-humidity environments, which matters on the Gulf coast and anywhere salt air gets to the underside of the roof deck.
The "RD" stands for rafter-or-deck. The screw is engineered to anchor HUG into a rafter for full structural pullout, into the deck where rafter spacing forces it, or through both layers. Either way, the EPDM washer compresses against the HUG halo to complete the waterproof stack.
You'll need one RD per HUG attachment, so order them in matching quantities. Sold individually here, not as a kit.

EZ Solar Rooftop PV J-Box (Asphalt Shingle)
The JB-1.2 is a flashed rooftop junction box for asphalt shingle roofs. Use it as the transition point between your rooftop module conductors and a conduit run heading to the inverter. The polycarbonate box mounts under the shingle with an integrated flashing skirt, so the roof penetration ends up under the next course of shingles and stays watertight. Rated 1000 VDC, 80 A, with a wire range of 14 AWG to 6 AWG. Type 3R enclosure, fits roof slopes from 2.5:12 to 12:12. One inch is the max conduit fitting size on both the side wall and the floor pass-through, which covers EMT, liquidtight, and most flex sizes you'd run on a residential array. Listed to UL1741 and CSA C22.2 No. 290. Operating range from -35°C to +75°C, which covers Gulf coast attic conditions year-round. Worth knowing: EZ Solar has discontinued the JB-1.2 and replaced it with the JB-F.100. The JB-1.2 still works fine on asphalt shingle and matches existing inventory, but for new designs going forward, the JB-F.100 is the newer part to spec.

IntegraRack BallastRack Frame IR-30
The IR-30 is a single fixed-tilt ground rack at 30 degrees. One frame holds one module (standard residential up to oversized 800W panels). It's 6061-T6 aluminum, ships in a 5"x5"x48" box at about 10 pounds, and the structural assembly goes together in under 2 minutes. The 30-degree tilt hits a year-round sweet spot for most of the lower 48: enough angle to shed snow in winter, not so much you lose summer production. The module slides up and down the frame for ground clearance, so you can clear tall grass, brush, or sand drift without redesigning the rack. You can anchor it four ways: EarthBallast pans (concrete blocks set on the soil), AnchorSpike for soft ground, drilled concrete anchors for slab, or IntegraRack EarthScrews for dense compacted soil. The EarthScrews are the fastest of the four on most sites; we stock those too. Engineered for 150 mph wind and 100 psf snow at the design level. UL 2703 listed for mechanical and bonding. Pairs with most standard solar modules without special hardware kits.

IntegraRack EarthScrew
EarthScrews are the fastest way to anchor an IntegraRack BallastRack frame to dense compacted soil. Drive each 30-inch screw with a standard impact wrench, set the frame leg over the screw head, level the array. No concrete, no curing, no pouring sand. One 10-pack anchors 5 BallastRack frames (2 EarthScrews per frame). Each screw is rated for up to 1,000 lbs of uplift. Test one on-site first to confirm the soil holds; IntegraRack recommends a 1,000 lb pull test before committing to the whole array. These need dense compacted soil with frost depth under 20 inches. They won't work in silty sand, soft fill, or rocky terrain. For extremely dense ground, pre-drill with a 30" SDS-Max carbide bit and add concrete mix to the hole for extra grip. A nice install detail: the screws allow vertical adjustment after they're driven, so you can level the array on slightly uneven ground without re-driving anything. Heavy-duty steel, built to outlast the modules above them.
