Extensive Testing
InfiniteRule products undergo extensive third-party testing to determine shear strength. The shear strength is determined by placing the locking pin in a stress position and subjecting it to increasing force until a required proof load (maximum force received without deformity) is met or the pin fails. These locks have a shear strength of 42,000 lbs.
