I used the Triag clamps in dedicated fixtures on our HMCs . We ran 24/7 production & never had problems with them. The only thing we ever replaced was the jaws which started to wear after about 12-18 months. I figured it's normal for as much as we used them. The company offers a variety of styles & sizes. We purchased extended jaws & milled a contour to match our part. The clamps are not cheap, but they outperformed any of the other clamps we were using before.
