Maximum Working Loads: are for rope in good condition with appropriate splices in non-critical applications, and under normal service conditions. Working loads should be reduced where life, limb, or valuable property are involved, or for exceptional service conditions such as shock loads, sustained loads, etc.

We splice all types of ropes!
