"WLL" stands for Working Load Limit. You may also see the abbreviated as "SWL" which stands for Safe Working Load. The two terms are interchangeable. Basically this represents the maximum force you should apply to the choker. It is not the same as Breaking Strength, which is often abbreviated as "MBS" or "ABS". Breaking Strength refers to the load at which the product will likely fail. The Working Load Limit is typically arrived at by dividing the Breaking Strength by 3, 4 or 5. The exact multiplier varies by product, and this is referred to as the Safety Factor, or Design Factor. Those two terms are also interchangeable.
