Models, codes and parameters

Codes are printed exactly as in the catalogue, so a repeat order can be matched line by line. Parameters are the ones the catalogue gives for each model; where the catalogue gives no figure, the cell is left out rather than estimated.

Selection notes

What to check before ordering

These notes come from the catalogue pages named above and from the fitting information printed with the same family.

Choose a notch-free hinge where the profile has no 20 mm euro notch; the 57A and 57A2 hinges are for profiles cut with the standard 20 mm notch.
Pick the hinge pair by sash weight with a margin rather than by window height alone: the catalogue load figure is a per-pair limit, not a window rating.
Concealed friction hinges (OHL.JL-001 and OHL.JL-005) are in the same catalogue section and carry 70 kg per pair; they are used where the hinge has to disappear into the profile.
