Is the lid or hatch on your toolbox, boat seat, or storage compartment getting weak and won't stay up? Time for an upgrade! This is a pack of two heavy-duty lift supports from Lift Supports Depot. Each strut is 30.5 inches long when fully extended (that's measured from the center of one mounting ball to the other). They're rated for 110 pounds of force each, and they're built tough with stainless steel bodies and 13mm ball sockets for a secure connection. They're even marine-grade, which means they can handle damp or salty environments without rusting out fast. Here’s the important bit: these are designed for lids that weigh roughly 55 to 74 pounds. If you're not sure what strength you need, there's a simple trick – use a scale and a board to weigh your lid where the strut attaches, then multiply that number by 1.5. That'll give you a good estimate. These struts are made to meet or beat the original equipment specs, so they'll last. Installation is usually a simple swap – just compress the old one (carefully!), unclip it, and clip the new one in place. Suddenly, your lid will pop open and stay open safely, just like it did when it was new. No more headaches holding it up with your head!
