★Suitable Range of Use -- Exceptionally sturdy! Ideal for supporting weights between 45 and 66 pounds! For lids weighing less than 45 pounds, install only one strut or consider a less robust set.

★Application Areas -- Appropriate for use in caravan shells, windows, caravan covers, caravans, beds, storage doors, elevators, basement door hatches, ship covers, and more.
