The saddle washer is a shaped washer that follows the crown of the corrugation of trapezoidal sheet and supports the screw where it is fixed through the crown — with ridge flashings, snow guards and flashings. Without a saddle washer the head of the screw and the EPDM washer (4.8×16 and 6.3×19) do not seat flat and the corrugation deforms. It is chosen according to the profile (T-18, T-22, T-35, T-45).

The clip is a steel tab that is nailed to the substrate and folded into the seam of the sheet, so it holds the sheet without piercing it; it is used for G-fold and for seamed roof sheet. Fixed clips hold the sheet in place, sliding clips allow it to lengthen in the heat. Made of galvanised steel Z275 to EN 10346.

They close the open corrugations of trapezoidal sheet T-35 and T-45 beneath the ridge flashing and at the eaves — birds and insects cannot get in, while the air from the roof space escapes freely. They are supplied as a set matched to the sheet profile, of the same galvanised steel Z275.

With the reducer from the roofing accessories: the transition from the square cross-section 11 × 8 cm (developed width 400) to the round Ø 100 mm pipe, onto which the bends, pipe connectors and pipe clips of the standard system to EN 612 then continue.
