Drive rods and transmissions

Transmission rods carry the movement from the handle to the locking points along the sash. They are made in standard lengths: pick the rod by window type, then the length that reaches the locking points. Corner drives, keep plates and connecting pieces (OHL.SK) are in the same catalogue section.

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.

Transmission rods OHL-20 / OHL-A / OHL-B / OHL-C

The catalogue prints the lengths made for each rod. The catalogue remark on every row is to choose the rod type by window type and to use the standard length.

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.

Rods are chosen with the handle set and the locking points together: a two-point sash needs a different rod length from a three-point sash of the same width.
Main transmissions (OHL.LJ), anti-error rods and corner devices are listed in the same section (pp. 115–122). Send the window type if you need those instead of a plain rod.
Corner drives, keep plates and connecting pieces are all printed with OHL.SK codes, so an existing order can be matched line by line.

Request the complete model list

Send the models you already use, or the window type and profile you are building, and we will answer with the matching codes, drawings and the trade terms for your order. Trade terms are quoted per order and are not published on this site.
