The Taylor Made Marine Gas Strut for Boat Hatches # 3691836 measures approximately 12-1/2 inches in the closed position, although an exact measurement is difficult due to the nature of gas struts, as you can imagine.

I spoke with UWS, and they did confirm that using one of the lower holes for the gas strut will prevent the lid from opening 100% of the way. They also said the aluminum used on the # UWS01020 is .058 inches thick.
