A release mechanism is provided for a fire protection sprinkler having a body, including an output orifice sealed with a seal cap. The body has two arms extending therefrom that meet at a hub having a preload mechanism. The release mechanism includes a lever having a first end mounted on the preload mechanism. The mechanism further includes a strut having a first end mounted on the seal cap and a second end mounted on the first end of the lever. A thermally-responsive element is mounted in a second end of the lever, opposite the first end, and the thermally-responsive element has a displaceable member extending therefrom, so as to contact the strut.
