Transmission rods

The rod is cut to the sash: the catalogue gives standard lengths and a cut-length formula per system, so the handle sits where the fabricator drills rather than where the rod happens to end.

Notes for this range

  • Standard lengths are printed per rod type; special lengths follow the cut formula for the system.
  • The catalogue writes rod codes both as OHL.20B and OHL-20B — it is the same part.
  • Lock-point count follows the sash size, not the rod.

Used in these window systems

Single parts or a whole set

Distributors order by code and quantity; fabricators send the window and take the set. Both are quoted the same way.
