Transport Grade 70
Special high-carbon steel chain with increased hardenability and improved resistance to wear which allows greater practical strength-to-weight ratio. Ideal for truckload securement and for use with towing, construction, logging, and farm applications. The chain is embossed at specified intervals with an approved grade indicator.

WARNING: Chain and accessories shown are not to be used for overhead lifting or for hoisting applications. Do NOT exceed working load limits.
PROOF TEST: The load (in pounds) to which the chain was subjected, in the as-manufactured condition prior to the time it left the factory. Under this test, a load has been applied in direct tension to a straight length of chain with a uniform rate of speed on a standard chain testing machine. The sole purpose of this test is to discover defects in the material or manufacturing process.
Every foot of Proof Coil (Grade 30), High Test (Grade 43) and Transport (Grade 70) chains are proof tested. Where attachments such as hooks or rings are desired for use with chain in sustaining loads, care should be taken to select the attachments of the type, grade and size compatible with the chain with which the attachments are intended to be used.
GENERAL WARNING: Low and high carbon steel, weldless and welded chain, and accessories made from assorted metals are intended to be used in tension or pull applications and are not to be used for lifting or hoisting purposes or when their failure is likely to cause damage to property or persons. Jerking or acceleration in the rate of application of a load multiplies the stress on the chain very rapidly and should be avoided.
