### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    A Fine Product
  

*by W***. on Reviewed in the United States on May 6, 2017*

Working perfectly from the start. I decided to use 2 Bayliss XLs on one long polycarbonate panel, weighing at 10 pounds. I thought that if either actuator failed it would be "tattled" by the other. On each end, a chain runs from an arm on the vent panel down to a sliding vent panel at the bottom of the greenhouse.  - When the panel opens, so do the bottom vents. My son in law deserves credit for his artistic build of this greenhouse for my daughter. Thanks Matt  PHOTOS included.  Bayliss is a precision product.  Wyman Cooper Nevada USA

    i hate plastic so much
  

*by M***E on Reviewed in the United States on July 21, 2016*

I have 8 working flawlessly now, and have had zero troubles! i don's know how i lived without these! my only complaints are that the threaded rod could be threaded further down to allow for higher opening temps, overall the unit could be heavier duty, and the plastic. all metal and then the parts that take the most pressure, the screw plates, are plastic! i hate plastic so much :(
