I installed one of these a few days ago into a Patio door along with a Cisa hookbolt. This was to replace the existing mechanism that is no longer manufactured. The cylinder is smaller than the "standard" Oval, with the face measuring 13mmx28mm.
Does anyone know of an escutcheon to fit these particular cylinders ?. If not, I may have to get some manufactured (ouch).
