Wichard HR Quick Release Snap Shackles

HR = Forged from 17.4ph top quality marine grade stainless steel with extra high breaking strain compared with normal marine grade stainless

HR = excellent breaking strain and durability

Forging reduces brittleness and maximises the internal tensile properties creating an enhanced stainless steel ideal for high load applications
Forged stainless steel normally deforms first when overloaded acting as a warning before the fitting fails.
A regular safety rig check by skipper or crew should therefore give notice of the impending breakage and create an opportunity for replacement before ultimate untimely failure

Wichard Quick Release Snap Shackles features:

• Totally smooth oval shape with a quick release lanyard mechanism
• Ideal for spinnaker sheet and guy applications
• Immediate release under load with a yank on the lanyard
• Available with standard size swivel eye or Large Bail Swivel Eye

N.B. the maximum line diameter for multiple lines in a large bail can be estimated from the figure B in the second list below

WLL = working load limit
MBL = Manufacturer Break Load
