Welcome to our "About" page. This page will serve to provide you a history of our company, as well as the values we stand for.


PMG was founded by Bill Blair, in Wheeling, WV. PMG was the third company Bill started. The first, Blair Enterprises which he started after serving in the USAF, was a radiator and air conditioning repair shop he started with his father, Reece Blair in 1960.

Through Blair enterprises, Bill was asked to repair oil coolers for some local coal companies. So he started applying different technologies and  ideas and a new industry was formed. The remanufactured oil cooler industry.

Bill was able to do what companies such as Caterpillar and Detroit Diesel had not been able to do. He started a company, Posi-Clean, which would later become PosiTech. Because of the success of PosiTech, Bill earned a spot on Inc. Magazine's 500 fastest growing privately held companies, as well as Entrepreneur of the Year for the state of West Virginia.

The beginnings of PMG

The origins of PMG was an idea of a consortium of small businesses. While there was some early success, the direction for PMG changed dramatically one day.

Bill was present with a prototype from the INEL (Idaho national engineering labs), for a product driven by then Attorney General, Janet Reno.  Ms. Reno wanted an alternative to stopping high speed police chases. The technology of the time called for an officer to stand on the side of the road, waiting for the target car. Then at the last second had to try to throw a spike strip in front of the target car only, and if successful, pull the spike strip back. The office had to try to hit the target car, and not other cars driving by. He or she had to pull it back quickly so not to also hit the pursuing police vehicle, a civilian car, while trying not to get hurt by the very spike strip he or she was trying to use. Ms. Reno knew that a number of police officers died trying to deploy these spike strips. In fact, one news article reported that a man fleeing police, said he saw the officer getting ready to throw out a spike strip and knew he was caught, so he was "going to take at least one of 'em out with me". He intentionally targeted this police offer with his car and killed the officer.

The new technology shown to Bill would allow for police to pre-deployed with the spikes covered. This meant the strip could be placed in the road at any time prior to the target vehicle approaching. Cars could run over the pre-deployed strip without damage. Since it could be pre-deployed and the spike were inactive, the officer deploying this new technology could go ahead, and either wait for a lull in traffic, or stop traffic to deploy he spike strip.

When the target approached, the offer would flip a handle and activate the spikes. The spike s would rotate 90 degrees and would deflate the wheels of the target vehicle only. Once the target went by, the officer would rotate the spikes back down, again covering the spikes and permitting the pursuing police cars to continue over the strip without damage to their tires, or to any one else's tires. Since the strip was now inactive gain, the strip could remain ion the road and the deploying officer could get in his or her car and assist in the end of the pursuit.

But the main benefit of this new system, was that it removed the deploying office from the side of the road. He could be 18 feet back. The officer could take a position of safety from behind their car, a tree or any barricade which presented itself. 

Mr. Blair envisioned an end to the days of officers being needlessly killed, or injured, in the line of duty trying to stop a high speed chase. Because of his father, this became a passion for Bill, and he changed his entire company to make this a reality.

The Son of a Police Officer.

What the presenters from INEL didn't know, but would soon discover, was the very personal connection Bill had with this product. Bill's father, Reece H Blair, was a WWII vet who served in the forward artillery. When he returned home from the war, Reece Blair became a police officer in the Wheeling police department. Reece earned a number of decoration and accolades, including being assigned to escort then presidential canidate Richard Nixon when Mr Nixon campained in the northern panhandle of West Virginia.

Mr Blair retired from the police force, and successfully ran for the office of county Sheriff. Mr Blair was reelected Sheriff. The time Reece was a police officer and Sheriff was a time of change as organized crime and mob bosses who were very powerful in the area were brought to justice.

The book "Murder Never Sleeps" depicts the rise and fall of a number of notorious mob figures from this community. These were people who then Attorney General Robert Kennedy was regularly updated on. Time magazine ran and article infamously declaring Wheeling and Steubenville Ohio as the "Twin Cities of Sin" due to the influence of organized crime.

For example, one time when Reece was Sheriff, Bill received a call from his father. Reece had received a tip that to get back at him, one of the local crime figures was going to discredit Reece by planting cocaine in the hub caps of Bill's truck.

So Bill spent most of his life knowing full well what it is like to be a family member of a police officer. He grew up as a little boy with the sick feeling in his gut if his father was late returning from his shift and an unexpected phone call or knock on the door came. Bill grew up with that fear family members keep deep down. So, when he had a chance to try and stop that knock on the door, that unexpected phone call, it became a passion for him personally.

The Road Spike

From here, the Road Spike was born. It became Bill's passion to get these out to as many police departments as possible. Unfortunately, the federal Lab(INEL) which licensed the product to Bill used a grommet to hold the spikes. This became the central figure in what would end up being a 10 year, $2 million intellectual property lawsuit. The result was the product was pulled from PMG. No one else brought a similar product to market.


While Bill had PMG develop other products such as the Road Blade, a multi-directional road access control device. They patented a portable speed bump, and developed one-way tire spikes (more below). But back in his mind, Bill still had a passion for the Road Spike.

Then one day he read where an officer was again killed deploying traditional spike strips. He did some research and quickly found that over the past 15 years, 26 different officers have been killed, and unknown amount injured. He contacted attorney's and found that the legal impediments to the Road spike no longer existed.
Free from the constraints of any legal entanglements, Bill decided to re-introduce the Road Spike.

Other Products behind PMG

PMG has been selling road security equipment for over 20 years. It has 2103 customers at last count. It is housed in space of one of Mr Blair's other companies, the PosiTech building.

The Portable speed bump was developed as a result of a school administrator seeing the Road Spike at a tarde show. She called and wanted a unit without spikes.he wanted to get the attention of distracted drivers who she felt were endangering her school children as they were dropped off and picke d up from school.

The Road Blade was designed for higher security facilities. These were designed for road access control points where an on-demand system was required to shut the road down in both directions when needed. The one-way tire spikes (much like you see at car rental lots- where you can drive one way, but not the other) are used for road and traffic control in applications from parking lots, to military base, to intermodals.  These products have helped stop the theft of cars from lots, protect the people and property at military bases across the globe and controlled perimeter security throughout the country.
