Review on 2Pcs 20" 55LB Gas Prop Struts Shocks With L-Type Mounting Brackets, 245N Lift-Support For RV Bed TV Cabinet Floor Hatch Garbage Storage Box Lid - ARANA by Ashwin Chauhan

I found an online calculator where I could enter the weight of the door and the dimensions and find the right size to order and about where on the door and frame to mount them. The door weighed 23 lbs at the handle and was about 30" tall. These are good sturdy struts and have worked smoothly and consistently since I installed them. Figuring it out wasn't as hard as I thought, and it was very satisfying to see it work.
