This is an Anchor Products Double Crimp Ratchet Tool Part No. 701030. This crimper is not as ideal for use on heat shrink connectors as the previous crimper but will work on them.
_
This crimper, as shown, is designed to crimp standard insulated connectors, often sold as "marine grade", from 22ga wire to 10ga wire. This tool allows for the barrel and the strain relief sleeve to be crimped, in one motion, and at the same time and will not release until the full crimp has been made.

One other key feature, of a high quality ratchet type crimper, is that you can simply re-calibrate when and if they ever go out of adjustment. You can also order different jaws or "dies" for this tool to crimp different types of terminations such as BNC or RG type cable terminations.
