Gregory J. Whalen has over 30 years of experience in the building industry. Greg has been a contractor of custom residential homes in the Black Hills of South Dakota. Consequently, he made some important observations that led him to invent and develop a new unique Fall Protection/Scaffolding system.

The design (called The WHALEN-JACKā„¢) was developed as a result of the experience of building in steep, alpine terrain. Scaffolding is essential in the construction of multi-level buildings but traditional scaffold is cumbersome, very expensive and takes to many man hours to erect and take down. The foundation of this invention is the ease and versatility as well as its broad application across a wide customer base. Besides the standard section scaffolding, other types of clever designs of fall protection and scaffolding exist, but have serious shortcomings for doing the complete job with the ease and versatility of The WHALEN-JACK.

In 2002 JD Systems, LLC acquired the license to manufacture and sell The WHALEN-JACK. JD Systems then partnered with a manufacturing facility. This was a win-win for JD Systems and its customers enabling us to have incredible quality control while also enabling us to fulfill any order of any size. Year to date JD Systems has partnered with some of the largest distributors in the United States, exposing our products to the largest builders in North America.

We look forward to the upcoming year and the broad customer base we are reaching. If you are interested in distributing The WHALEN-JACK feel free to contact us. Thank you again for your interest in The WHALEN-JACK!
