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.)
