Why does a double-wrap choker hitch provide more secure grip on smooth cylindrical loads than a single choker?
A
The double wrap increases the contact area between sling and load, distributing friction over a longer section and providing more grip stability
B
The double wrap creates two separate constriction points that prevent the load from sliding through the hitch even if one wrap loosens
C
The double wrap increases the rated capacity by a factor of 2
D
Double wrap chokers are only used when the load exceeds the single choker's WLL
