This vent opener fits the majority of free standing greenhouses and larger lean to greenhouses which are at least 4' deep but not smaller reach in or lean to greenhouses or cold frames. This is because the cylinder hangs down and protrudes whenever the vent is not fully open. In a smaller lean to greenhouse e.g. 2'x4' or 2'x6' the cylinder would be obstructed by the front wall. No guarantee is given that it will fit a particular model.
