Synthetic Round Slings are rated for use at what temperature range?

• A. 0 to 150 F
• B. -40 F to 0 F
• C. 100 F to 300 F
• D. 194 F to -40 F

Answer: (D)

Synthetic round slings are made from fibers that can lose strength or become brittle when exposed to temperature extremes, so they must be used within a specific temperature window to maintain rated capacity. The standard rating for these slings covers from -40°F up to 194°F (-40°C to 90°C). Below -40°F the material can become stiff and fracture-prone; above 194°F the fibers may soften or creep, reducing strength and stability during lifting. Among the options, the range that matches this safe window is -40°F to 194°F. Other ranges either exclude the cold limit or the hot limit, or extend beyond what the manufacturer typically guarantees for synthetic round slings.
