About Us

Russell Barnes had been a logger for over 30 years. By 2013, he had grown more and more frustrated with greasing the 75 fittings on his Rottne SMV Harvester. He was wasting grease, time, and energy and he vowed to find a better way.

Russell teamed up with the South African inventor of a new locking grease coupler to bring their product to North America and create the LockNLube brand. Since then, the LockNLube Grease Coupler has gone through several iterations, each time improving in response to feedback from our customers: the farmers, loggers, truckers, and others who grease their machines every day.

What started with one revolutionary product has grown to encompass our mission to “End Greasing Frustration”. We are a family-owned business with deep pride in our work. We build and source long-lasting tools to make our customer's lives easier and their work less frustrating. We stand behind what we sell with customer service, a satisfaction guarantee, and a commitment to selling only the highest-quality equipment.

Our business is located in New Hampshire, just down the road from where we started, in Russell's living room. Our team is available 9–5 Mon–Fri to answer any questions you might have. Give us a call at 603-795-2298 or email us at

In a world dominated by cheap imports, outsourced call centers, and copycat designs, we believe there is a better way to do business. We prioritize quality in everything that we sell. This means working with suppliers and manufacturers around the country, and the world, to make our products work well and last for a long time.

When the assumption is that businesses will do what they can to avoid accountability, we take the opposite approach. We respect our customers, our suppliers, our employees and our community. Have a problem with our products? Call us and we'll make it right. We'll probably learn something from you too, and can use that to make our products even better.

If you've read this far, thanks for taking the time to learn about the company you are buying from. We love what we do and think that comes through in our product quality, fast shipping, customer service, and product support. If there's something we could be doing better, please let us know.
