The IR-T1 replaces the traditional tile hook on concrete tile roofs without removing a single tile or drilling into the deck. It bonds nested tiles into one ballasted foot and clamps down with two tension bolts, so each one-piece bracket goes up in under two minutes.

The IR-T1 replaces the traditional tile hook on concrete tile roofs and carries a solar array without drilling into the deck or pulling tiles. Instead of penetrating a rafter, it bonds and clamps to the existing tiles and turns their weight into the anchor. The roof's water seal stays intact, and a typical mount comes down to about two minutes of work.
Each one-piece bracket slides its two integrated hooks under the upper and lower courses of tile at a single location. A bead of IntegraGel concrete adhesive bonds those tiles together, and the overlapping tiles around them nest the assembly in place. The result is one heavy ballasted foot built from multiple bonded concrete tiles, holding the mount down by mass rather than by a fastener driven into the structure. Two tension bolts clamp the bracket to the tile and give it enough holding strength to load modules right away, before the adhesive has fully cured. A built-in flex point lets those bolts tighten against the tile without cracking it.
Load capacity scales with how closely the mounts sit along each rail. At one mount every 6 feet, the IR-T1 is rated for 120 MPH wind and 10 lbs per square foot of snow. Tighten that to one mount every 4 feet and the rating climbs to 150 MPH wind and 15 lbs per square foot. Each mount supports a solar module up to 24 square feet, and resists roughly 175 lbs of direct uplift. The bracket's holding strength was validated in aeronautical wind tunnel testing. Designers working in high-wind or heavy-snow regions should set mount spacing from these figures rather than defaulting to the 4-foot maximum.
The IR-T1 is built for concrete tile and fits flat, S, and W profiles. Tiles need to be at least 1.25 inches thick with row spacing between 11.75 and 15.5 inches, which covers most concrete tile roofs. The ballast method relies on the weight and overlap of concrete tile, so the bracket is rated for concrete only. It is not compatible with clay tile, including Spanish clay profiles. Because the mount transfers load into the tiles rather than the rafters, the existing tiles need to be soundly fastened to the deck before installation.
The current IR-T1 is a single piece: the two mounting hooks and the rail upright are formed as one, with no separate foot to assemble or slide. The upright carries an open height-adjustment slot that takes the T-bolt from your rail system, the same way a standard tile hook does, so it works with any standard rail, including IronRidge, SnapNrack, K2, and Unirac. Rails and their T-bolts are sold separately.
A single mount installs in under two minutes: bond the tiles with IntegraGel, slide the bracket's two hooks under the upper and lower tile rows, tighten the two tension bolts, and attach your rail to the integrated upright. The tension bolts hold firmly enough to load modules before the adhesive cures, and the integrated flex point keeps that bolt tension from cracking the tile. One tube of IntegraGel covers about ten brackets and is sold separately; IntegraRack IntegraGel is the matched adhesive and stocked here. Grounding and bonding are the installer's responsibility: provide a direct-to-earth ground per NEC 250 and NEC 690, and keep bare copper grounding wire off the zinc-plated steel to avoid galvanic corrosion. The IR-T1 conforms to UL 2703 mechanical and bonding requirements and is backed by a 25-year limited warranty.
No. It is rated for concrete tile only. The mount works by bonding to and ballasting against the weight of concrete tile, and clay or lightweight tile does not provide the same mass or bonding surface. It fits flat, S, and W concrete profiles from 1.25 inches thick with 11.75 to 15.5 inch row spacing.
That depends on how tightly you space the mounts. The engineering datasheet rates the system to 120 MPH at one mount every 6 feet and 150 MPH at one mount every 4 feet, each paired with a snow load limit. The bracket itself survived over 165 MPH in wind tunnel testing with a 3:1 safety factor, but design your layout around the datasheet ratings tied to your actual spacing and snow load.
The system carries the array through the tiles, so the tiles have to be soundly fastened to the deck first. Screwed or nailed tiles that sit tight to the roof are a good candidate. Loose tiles, or batten-hung tiles with no anchoring, should be secured before the mounts go on.
The IR-T1 conforms to UL 2703 mechanical and bonding requirements, so it carries the equipment grounding path through the mount and rail like any listed rack. You still provide a direct-to-earth ground per NEC 250 and NEC 690. Keep bare copper grounding wire away from the zinc-plated steel to prevent galvanic corrosion.
A high-strength concrete adhesive, applied where the bracket tabs bond the tiles together. One tube covers about ten brackets. It is sold separately; [add-to-cart id="55808" text="IntegraRack IntegraGel"] is made for this use.
IntegraRack IR-T1 - Revolutionary solar panel Tile Roof Hook Mounting System
IntegraRack Overview video by IntegraRack
It was very easy to install. I was skeptical at first find because I've only put in traditional tile hooks and had to notch the tiles which is very difficult and risky. Three of us put up 22 Aptos panels with Ironridge rails and got it done by lunch. On normal installs its a whole day to get just the mounts in and then the next day to put the rails, microinverters and panels up.
