Hinges and pivot hinges
Pivot hinge pairs for tilt and turn and casement sashes, notch-free side-hung hinges, and heavier hinges for doors — each with the leaf size and the load per pair printed beside it.
What the catalogue covers
Hinges carry the sash, so the catalogue prints a maximum load per pair for each model next to its drawing, together with the sash-to-frame gap it needs. The figures below are those printed values; the real load of a finished window also depends on the profile, the glass and the fixing method.
The H-370 pair works as a set: the bottom pivot hinge OHL.H-370A carries 80 kg and works with OHL.H-370B for tilt and turn sashes, with 3.5–5 mm between frame and sash.

Load figures are the maximum per pair printed with each drawing in the catalogue; the window profile, the glass and the fixing method all change the figure in practice, so the set is confirmed against your sash. Door hinges in the catalogue reach 180 kg; that model is in the full list sent with the quote.

Before you order
Three things decide whether a part fits: the profile it is screwed to, the sash it has to carry, and the set it belongs to.
- Notch-free hinges do not need a notch cut into the profile, which keeps the profile wall intact.
- The sash-to-frame gap is printed with the pivot hinges: 3.5–5 mm on the H-370 pair.
- Hinge positions follow the sash height and weight; they are marked on the drawing we send with the order.
