Review on 🔍 Maxpow C16-10944 Gas Prop Force 80 lbs per Prop - 35.43 Inches - Lift Supports Struts for Camper Rear Window and Tonneau Cover - Please Verify Extended Compressed Length and Force Prior to Purchase by Anthony Robichaud

I used this pair to raise a 40 lb swing door. At the hinge point to the strut pivot, the door design weight down is 120 lbs. These struts together carry a load of 180 pounds, keeping it light, but it only takes 5 pounds of downward force at the end of the door to close it. So you're holding the door with 60 pounds of force, but only need 5 pounds of force at the end of the door to close it. Easy! As long as you understand the power of leverage and time your project, these racks are exactly what they claim to be. Online calculators will also help you with the math. Much luck!
