This was a replacement for a faulty cylinder piston, fitted in less than a minute, only time will tell if it works ok as it's still quite cold at the moment.

Brought to replace the cylinder on a non- working greenhouse window cylinder. Arrived promptly, was easy to fit and works perfectly. An excellent but.

This replaced an original cylinder that failed after only 7 years... Perfect fit, perfect function. I'll report back if this one doesn't do as well as the original. ;)Good value, especially when compared with the cost of a whole replacement lift mechanism from Juwel.Easy to install:-- Squeeze and release the mechanism from the front face bracket.-- Remove the lid section from the cold frame and flip it so the mechanism faces up.-- Remove the locking clip that secures the end of the rod in the middle of that mechanism.-- Unscrew the old rod from the nut in the middle, noting the direction the cylinder threads in to it.-- Chill the new cylinder in the fridge/freezer so it is fully collapsed.-- Thread the new cylinder into that nut in the middle, noting the same direction. For some reason mine threaded in one way a lot more readily than the other.-- Manually flex the mechanism open to allow the end of the cylinder rod to fit into the same hole the old rod passed in to, and reinstall that clip to secure it there.-- Replace the lid section on the cold frame.-- Re-engage the mechanism with the front plate by gently squeezing those two arms together, and engage the pins in the holes in the front plate.Takes just minutes with the cylinder cold. There's more fight than you need if you are trying to wrestle a warm extended cylinder against the lift springs. Chill for a few while it chills for a few, and you'll find it's much less of a fight.

Attention, il s'agit juste du verin sans le mécanisme vu sur quasi toutes les photos

Sur la photo on voit le mécanisme entier en réalité il n'y a que le vérin dans la commande. Je suis tombé dans le piège!

Der Ersatzzylinder ist insgesamt 34,2cm lang. Der Durchmesser des Zylinders ist 16mm.Die Kolbenstange ist eingfahren 10cm lang und 6mm im Durchmesser. Bei Temperaturerhöhung im Gewächshaus dehnt sich die Flüssigkeit im Zylinder aus und drückt die Kolbenstange heraus, wodurch sich das Fenster öffnet. Mir gehen die Dinger immer im Winter kaputt. Es wirdempfohlen, die Zylinder im Winter auszubauen.
