Testrite Instrument Co., Inc.

Testrite is very proud to be an American manufacturer with an extraordinary reputation for quality, value and reliability. As an Instrument company, we service a wide range of industries.  We source the finest quality components, and because we manufacture in the U.S., our supply chain is shorter, “greener”, and we can offer customizable solutions.

Testrite – Founded in 1919
CEO Larry Rubin and his son, President Jeffrey Rubin (fourth generation) continue the Company’s tradition of high ethical corporate responsibility and an unwavering dedication to customer service and innovation.  Benefit from our over nine decades of experience and a huge stable of in house tooling.
Telescopic Aluminum Tube Manufacturing
Originally a photographic tripod manufacturer selling products through such companies as Sears and Montgomery Ward in the 1950s and 1960s, we eventually decided to specialize in the manufacture of telescopic tubes and accessories made to order.
Today, customers specify desired open and closed dimensions, diameters, number of sections, type of lock, and any additional processes (e.g. holes) or components needed (e.g. threaded connectors, bases, end caps, etc.), and receive quotations back the same day.
Other Capabilities
Testrite is an integrated metal manufacturer.  In house capabilities include wire forming, automatic screw machining, forming, welding, tube bending, tool and die manufacturing and much more.
Core competencies beyond the manufacture of telescopic tubes made to order are fabrication and design of aluminum extrusions, custom stands and devices, light boxes for the display industry, and helping to develop the next new new thing whatever it may be.  Remember - benefit from our over nine decades of experience and a huge stable of in house tooling.
Packaging, kitting, and drop shipping are all available.  OEM products are quoted bulk packed by component unless otherwise specified.  Testrite can provide full logistical support.

We pride ourselves on listening carefully to our customers and responding to their needs by developing innovative products built to last at value price points.
