Widely recognized for their first-rate materials, design and workmanship, Wichard products are highly documented, ISO 9001 certified, and backed by a 5-year warranty. All Wichard snap hooks are hot forged and passivated, providing exceptional reliability, eliminating internal structural defects and protecting against oxidation. NOTE: the gates on these particular carabiners are significantly stiifer to operate than other carabiners.
SWL is maximal static load without deforming
BL is static load at which total failure, by rupture or deformation, occurs
Standard Snap Hooks are made of 316L stainless steel alloy
Safety Snap Hooks are made of Wichard's HR, high resistance, 17.4 PH alloy, one of the strongest available in marine hardware. This slightly magnetic alloy is used in Wichard's top-end products. (Note: the second hole in the Safety Snap increases the structural strength, but has no function in use.)
