This latch is made of heavy metal but does not have the correct angle to engage. The closure is at an angle of less than 90°, making it easier to open. As another user wrote, if you join something that moves, it will unlock. I modified mine with a grinder and it's much better now, but I don't recommend it unless you're mechanically inclined or don't have a grinder handy. I will also attach a pin to mine to secure it properly. I do not recommend this purchase.
