We now have available 2 different Wall Chart versions: one with Chain Slings rated at a Design factor (DF) of 4:1 and one with Chain Slings rated at a DF of 5:1.
Note that Chain Slings with a DF of 4:1 are specified in ASME B30.9, ASTM A 952, NACM 2010, EN 818-4, the US OSHA and all other Canadian Provincial Health and Safety Acts (other than the exception of the construction industry in Ontario, as noted below).

The reason for having a second WLL Chart rating Chain Slings with a DF of 5:1 is that in Ontario the OHSA for Construction Projects demands it.
ALL other industries and applications are rated with a DF of 4:1.
Quebec:
The reason for having a second WLL Chart rating Chain Slings with a DF of 5:1 is that in Quebec the Greage et Levage for Construction Projects demands it.
