This screws into my automatic vent opener and fits like the original. This is great because it saves me from taking down and installing a new opening hinge because of a failed cylinder.Great replacement part

I have a few automatic vent openers in my greenhouse. One of my vent opener cylinders busted open last year. I thought I would have to buy a whole new kit to get a replacement. This cylinder looks the same and fits the same as the original oem one. Hope it works as well and lasts even longer than oem. If it fails in the first season I will revise my review, but the part looks good to me.
