About Sling Link

Our History

The Sling-Link MAST was designed and tested by veteran San Antonio Firefighter Ken Dempsy, who realized the need for a new type of tool for saving lives.  Originally designed for the "Save Our Own" program, the MAST now meets NFPA Standard 1983 (06 Editon) as a Personal Use  or General Use Auxiliary Harness, and is a OSHA approved lifting sling.
