Calculator is amazing!
The calculator was SUPER useful, I managed to put two different calculations together for gas springs in two different locations. I've had a rigged trap door into my root cellar for years, but after adding trex decking it became insanely heavy. I wish I had found this site years ago when I first put in the door and rigged some gas struts, it would have saved me so much time! Gas springs and attachments seem super high quality and well built.
