TRT Tile Hook System TRT03 for S, W and Flat Tile Roofs

TRT Tile Hook System TRT 03

TRT Tile Hook System is a solar mounting solution built specifically for tile roofs, accommodating flat tiles, S tiles, and W tiles. The system uses high-quality aluminum and stainless steel 304 components, with three tile hook variants designed for different tile profiles. Tiles may need to be removed, adjusted, or notched to ensure proper fit around the hook during installation. The TRT Tile Hook System is UL 2703 listed, PE certified, and maintains the fire resistance rating of the existing roof. For base spacing and layout requirements, always reference TRT’s PE-certified span tables.

The universal panel clamp fits modules from 30 to 40mm in thickness and functions as both a mid-clamp and end-clamp, simplifying component management across the installation. Optional accessories include cable clips, bonding jumpers, microinverter racking kits, and wire management components. Before specifying your system, review how wind and snow load requirements affect tile roof solar mounting in your region.

Frequently Asked Questions

Which tile hook do I need for my roof type? +

TRT03 includes three hook variants. Tile Hook 1 (3010369) attaches directly to TRT Rail with multiple adjustment options and is compatible with S and W tile profiles using 5/16" x 3" or 5/16" x 4" lag bolts. Tile Hook 2 (3010370) is made from stainless steel 304 and is designed for W or S-shaped tiles with the same fastener options. Tile Hook 3 (3010371) is made from stainless steel 304 and is designed for flat tiles. Always verify your specific tile profile against the TRT installation manual before ordering.

Do tiles need to be removed or modified for TRT03 installation? +

Yes. Tiles may need to be removed, adjusted, or notched using a grinder or cutter bar to ensure proper fit around the hook during installation. TRT03 is designed to preserve the tile roof's water management function, but installers must follow the TRT installation manual for the specific tile removal, hook placement, and tile reinstatement sequence for each tile profile.

Is TRT03 compatible with all panel sizes and thicknesses? +

TRT03 supports panels up to 1722mm x 1134mm with frame thicknesses between 30 and 40mm. The universal panel clamp functions as both a mid-clamp and end-clamp, with no restrictions on module size or thickness within that range. The hidden end clamp secures modules to rail ends with a fully hidden bond. Always verify your module specs against the TRT compatibility documentation before ordering.

How do I determine hook spacing for TRT03? +

Hook and base spacing for TRT03 is determined by TRT's PE-certified span tables, which account for local wind speed, ground snow load, panel configuration, and roof framing. Hooks are fastened into the roof framing member using the specified lag bolts with sealant and sealing washers as required by the manual. Do not use field estimates. Request stamped calculations for your specific project if required by the local AHJ.
