Our History

6-inch [15 cm] vacuum cup prototype.

In 1947, Howard Wood opened Wood’s Auto Electric, an automotive, electric and small engine repair shop in Wolf Point, Montana. After years of frustration while trying to hold small engine valves during the lapping process, Howard designed and built the first Wood’s Powr-Grip Valve Grinder in the early 1960s. The tool consisted of a small, spring-action vacuum pump mounted in a wooden handle, opposite a rubber suction cup which attached to the flat surface of an engine valve.

At first, he simply built these tools for himself and friends, but soon the public was demanding the unique little tool. As the popularity of the Powr-Grip Valve Grinder grew, a glazier friend suggested Howard develop a vacuum cup for handling glass.

Howard experimented and developed vacuum cups in a variety of sizes. It wasn’t long before the glass industry took note of the invention. These cups possessed a unique red-line vacuum indicator on the pump that warned the user if vacuum loss occurred, and a check ball that restored lost vacuum without breaking the cup’s grip. Neither of these features—the trademarks of today’s Powr-Grip vacuum cups—were available anywhere else in the world at that time.

Early tests of the battery-powered, sealed foam lifter.

Howard began manufacturing vacuum cups for glass handling in 1963, incorporated the business in 1964, and obtained a patent for his design in March 1966. The cups were first introduced to the American market by traveling salesmen. As popularity grew, the vacuum cups appeared in national and international glass handling equipment catalogs.

In the late 60s, Howard developed and patented a battery-powered, sealed foam vacuum lifter for use with overhead cranes and hoists. Capable of handling loads up to 600 lbs. [270 kg], this design was the first of many below-the-hook vacuum lifters. Over time, a wide variety of manual, AC, DC and air-powered vacuum lifters were designed and built to accommodate an ever-growing market.

Howard died in Wolf Point on January 28, 1983, at the age of 73. The company moved from Wolf Point to a larger facility in Laurel, Montana in 1990 and maintained Howard’s founding principle of “doing the right thing” for customers, employees, and everyone who comes into contact with WPG products. Wood’s Powr-Grip is now under a third generation of family management. Our vacuum cups and below-the-hook vacuum lifters can be found in nearly every country in the world and have become standards in the glass industry.
