These 2 pcs gas struts provide stable support for your lids, allowing them to open softly up to a 100-degree angle. They are designed for a wide range of applications, including RV bed platforms, floor hatches, outdoor benches, cabinets, and tool boxes. With a force of 100N/22lbs per strut and a length of 9-11/16 inches (extended), these black gas springs are built to last, capable of withstanding temperatures ranging from -11℃ to 50℃. They undergo up to 50,000 factory inspections to ensure high quality. Please verify the size before purchasing, as the 10-inch measurement refers to the extended length, not the cylinder length.
