Why choose the F-TH01 pantile hook?

F-TH01 is the stocked LAMPS SKU, while TH01 is the Fastensol article reference shown in the roof hook guide. Listing both codes on the product page helps installers match the item to a quote, take-off sheet, Fastensol drawing or replacement component request without changing the sellable stock code.

This hook is for pantile portrait applications. It should be selected by roof covering and fixing method, not by appearance alone. Pantile, flat tile and slate roofs need different fixing approaches, so F-TH01 should not be treated as a general tile hook.

How does it work with GS Roof rail?

The hook provides the roof-side fixing point before the rail and module clamps are installed. In a typical GS Roof assembly, the hook is fixed to the timber structure, the mounting rail is secured to the hook, and the framed module is then clamped to the rail.

This makes the hook one of the structural starting points in the array. The installer should confirm hook spacing, rail spans, module orientation, fixing positions and site loading before ordering the final quantity. The Fastensol system data should be read as part of the complete mounting design, not as approval for every roof condition.

What should be checked before installation?

The roof survey should confirm tile profile, roof pitch, timber condition, rafter position, tile clearance and weathering route. Fastensol guidance shows roof hooks fixed with wood screws and notes that fixed hooks must not be used as ladder points because point loading can damage the tile below.

Tile cutting or relieving may be required where the hook passes through the covering. That work should be completed carefully so the finished fixing does not leave the tile sitting on the hook or introduce a point load into the roof covering.

Ordering with the rest of the system

F-TH01 is normally ordered with Fastensol mounting rail, universal clamps, rail splices and rail end caps where required by the project design. For wider system parts, browse Fastensol GS Roof or view the full solar mounting systems range.
