Product Overview
Grade 30 Proof Coil Self Color (Regular Link). Electronically welded proof coil chain. Finish is self color. Meets or exceeds NACM or ASTM standards. NOT to be used for overhead lifting. NEVER exceed published working load limit.

Introduction
Grade 30 Proof Coil Chain is made from low carbon steel and is a general utility chain for uses such as farm, log chain, tow chain and switch chain.

Caution
Do Not Use for Overhead Lifting. DO NOT EXCEED THE WORKING LOAD LIMIT.

Parameter

• Grade of Chain: NACM (National Association of Chain Manufacturers) & ASTM (American Society for Test Materials) classification
• Working Load Limit (WLL): rated capacity — maximum working load that should be applied in direct tension to an undamaged straight length of chain
• Proof Test: manufacturing test force — minimum tensile force applied during manufacturing as an integrity test (not for service/design)
• Minimum Breaking Force: manufacturer’s acceptance test result (not a service/design guarantee)
• Overhead Lifting: not permitted for this product (lifting that could cause injury or property damage if load is dropped)
