The Protean Series™ Data Receptacles is a family of multi-gangable ever changeable self-retaining receptacles.

Initial Installation

Why Protean

Sherman Industries created the Protean Series™ Data Receptacles because it didn’t exist. As TV’s have evolved into HDMI & beyond, our in-wall cabling is still based on the coax system. A person spends thousands of dollars on a TV & then has the cabling hanging down the wall.

Our Mission

Data receptacle innovation offers a huge opportunity. Despite our many technological advances, data receptacles, the key to cable management, haven’t changed much in 60 years. They are obsolete the day they are installed. We spend money on the latest technology and manage it with an obsolete installation. Sherman Industries exists to fill that need.

Our mission is to provide our customers a data receptacle that has their current and future needs in mind. Ours is a dynamic, infinitely adaptable receptacle that can change as fast as technology, thus mitigating unnecessary expense, demolition, and downtime. We would provide a timeless value to our customers.

We will build a profitable business that adheres to the highest ethical standards, with a commitment to give back to our communities. As we grow into a global company, we intend to be a leader in global citizenship as well.

Current data receptacles do not provide for adaptability or future expansion.

Our product addresses both of those concerns. The product is a finished receptacle yet classified as a supporting device. The receptacles are single gang, left, center, & right. For example, if a two-gang receptacle is installed and later there is a need to expand the system, simply remove the piece of wallboard, slide the right side over, and insert a center section. This process may be repeated numerous times.
In the above described process, expandability, normally requires expanding the internal support structure. My receptacles include a clip. As the system is expanded, each section is self-retaining. The unique design, & exclusivity of this product is that it eliminates the need to install a supporting structure in the wall, prior to installing the product.
The clip may also be removed for installation into an existing support structure. This product uses keystones, with the keystones, the product is forever adaptable. This product allows for infinite expandability, adaptability, & simplicity of installation. It is the only self-retaining & gangable patented product in its classification.
