BIBISTORE Auto Vent Greenhouse Window Opener with Two Springs So

BIBISTORE Auto Vent Greenhouse Window Opener with Two Springs So:leading global athletic footwear and apparel retailer. I had a heavy double-glazed patio door that I wanted to use as a coldframe. I estimate that it weighs about 50 pounds, so I was looking for lifters that could take it. I bought 2 lifters, since they were rated at 30 pounds of lift and the glass door would weigh less than 50 pounds when hinged. Since it was a coldframe, I wanted to easily lift it open without detaching the arms, so I purchased a couple of caster wheels and went to work. I had to drill out the rivet pin holding the mounting plate to the arms and then attached the wheels with screws. Since the sun hits the left lifter first, it will open the glass on its own and both lifters have opened about 10" at mid-day so far. The outside temperature was 65 degrees on this day and I have the pistons screwed in all the way. All my friends are impressed with these lifters too and I expect to get some good greens during the cool Connecticut spring.max 83% off,las vegas mall,max 77% offBIBISTORE Auto Vent Greenhouse Window Opener with Two Springs So
