Small Runs Are No Problem

Unlike many companies who have minimum orders of 100,000 or more units, we have the ability to fulfill small batch orders to provide quality service to smaller customers. Our equipment also allows us to complete the order efficiently so that it gets to our customers as soon as possible. 

“We are considered a high-speed filler in many of the markets we serve. For many of the products we manufacture, our competitors are not able to fill at the rate we can. While other companies could be filling two products every five seconds and filling 100 to 120 products in a minute, we can fill fives times that amount.”

Ranson Bradford, Director of Business Development for Commercial Construction Products

Quality Products

All of the products Red Devil manufactures undergo extensive quality checks before being distributed. In our laboratories we do our part to make sure each element, down to the raw materials, is checked to make sure it meets the manufacturers’ specifications before it continues to our production floor. We are also diligent about keeping a samples of products on a batch by batch basis for one year so that we have the ability to identify and rectify quality complaints.

Our company is also committed to making sure our manufacturing operations also adhere to ISO 9000 standards.

"Quality is of the upmost importance to our company. Our employees learn how to manufacture products correctly and safely first and foremost. Productivity comes with time – having a number of long-term employees as well as automated processes helps us be productive and continue to provide our customers with the best products possible.”

Alan Crupper, Vice President of Marketing

Centrally Located & Made in the USA

Many of our customers appreciate the fact the our manufactured products are made in the USA. Due to our manufacturing plant based in the heart of Oklahoma, we have the added bonus of being centrally-located, which allows us to ship products to just about any location in the country in a timely manner.

Private Label Options

“I think that what helps us the most is the fact that we can turn on a dime. For example, we are the only caulking and sealant manufacturer in the United States that makes its own caulking cartridges. This capability is one of the things that helps us turn products around within a day or two as opposed to taking two to four weeks.”

Alan Crupper, Vice President of Marketing

At Red Devil, we focus on providing benefits to our customers that our competitors may not offer. Many of our products, including our duct sealing line, have the option of being private-labeled with the brand of your choice. For clients who need their product manufactured in a specific color,  we have the ability to offer our products in more than 300 colors and offer a custom color-matching option for our acrylic caulks and sealants products.

To ensure high-quality packaging, we operate injection molding machines to produce caulking cartridges. Offset printers are used to place simple text directly onto cartridges; digital printers are used for more complex photos and graphics. If needed, our in-house graphics department is equipped to provide our private-label customers with a fully finished product. Whether they are using art provided by the client or creating original artwork,  this team consistently provided a custom product that meets and exceeds client expectations.
