Which item is typically rated for temperatures up to 180°F?

• A. Fiber core wire rope
• B. Chain
• C. Sling
• D. Endless sling

Answer: (A)

Temperature ratings tell you the maximum heat at which gear can be used without weakening it. Fiber core wire rope is rated for about 180°F because heat can degrade the rope’s lubricant and the organic fiber core inside the rope; when the lubricant breaks down or the core is affected, the rope loses strength. That makes it the item typically specified to be used up to 180°F in standard practice. The other items rely on materials with different heat tolerances—synthetic slings can soften or melt at lower temps, while chains and other metal components have their own different ranges—so they’re not the standard 180°F option in this context. Always match the exact rating to the product you’re using.
