We have maintained the high standards of quality of our insulators from the original to our newest model. We are committed to the high standards of quality set forth by our founder. H. J. Hirtzer & Assoc., Inc. is proud to protect crane handlers and equipment throughout the world.
We are committed to protecting the crane riggers and owners by providing tested and proven safety equipment and will continue to our best ability to do so.
We pride ourselves on the quality of our design and workmanship and look forward to meeting or exceeding any OSHA certification requirements as they become available to our industry.
OUR LINKS ARE BUILT TO NAVY SPEC NORDIV-4010-63-1
We are the only Link Manfacturer to build an Insulated Link that stops RF
CURRENT OSHA CERTIFICATION INFORMATION:
Because insulating links previously have not been required by any OSHA standard, OSHA has not yet recognized any testing laboratory as a NRTL for purposes of insulating link listing, labeling, or acceptance. A period of time will be needed to review laboratory requests for such recognition. Once there are NRTLs for testing insulating links, some time will also be needed for the NRTLs to conduct the tests. As a result, where §1926.1408(b) applies, §1926.1408(b)(4)(v) will be unavailable as additional measure in the list contained in § 1926.1408(b)(4) until employers acquire NRTL approved insulating links. Therefore, during that period, in addition to implementing the requirements in § 1926.1408(b)(1)-(3), the employer must implement at least one of the measures listed in § (1926.1408(b)(4) (i)-(iv).

As of September 6, 2013 UL has withdrawn it's UL2737 standard. UL did not give a reason, but this makes the ASTM Standard, the Standard.
ASTM has passed the new standard for insulated links, we are waiting for the standard to be published.
