A-342

A-342 and A-345 Master Links incorporate markings forged into the product which address two (2) QUIC-CHECK™ features:

Deformation Indicators - Two strategically placed marks, one on each side of the link, which allows for a QUIC-CHECK™ measurement to determine if the link dimensions have changed, thus indicating abuse or overload.

To check, use a measuring device (i.e., tape measure) to measure the distance between the marks. The marks should align to either an inch or half-inch increment on the measuring device. If the measurement does not meet this criteria, the Master Link should be inspected further for possible damage.


Angle Indicators - Forged at 45° angles at each end of the link, they are utilized to quickly check the approximate included angles between two sling legs.
