No drilling into the roof — no voided roof warranty, no leak point. One part instead of three from three catalogues you have to match yourself. Built for the standing-seam metal roofs common across the Baltics, Nordics and DACH — Rheinzink, PREFA, NedZink and the Klassik profiles.

Seam step is the distance between two seam folds. Measure yours, then pick Standard (270–550 mm) or XL (551–600 mm). On a narrow step the mount simply grips every second seam. Both models: seam height 23–37 mm.
Standing seam is not one profile. The clamp grips the fold itself:
Two numbers to check: fold height (mm) and seam step (mm). Fold height should sit in our published working band for the Orima CHA077 clamps; seam step picks Standard vs XL. Some industrial profiles (e.g. Kalzip, BEMO N50/N65) sit outside the ranges we support — we would rather say no than sell a mount that will not work.
