McLean HK Snaphook 1.25″ HK Snaphook. Designed by McLean Corp USA. After constantly battling with inferior HK Snaphooks that constantly warp and break, we decided to design our own that we would be proud to put our name on. Almost 4mm thick and made of non corrosive stainless steel. This Snaphook broke the strength testing equipment after 500 lbs.
