Thanks, Chris, and good morning to those of you who have joined us on the phone and those participating via the Web. We released Eastern's third quarter results and a full Form 10-Q yesterday afternoon, and we'll discuss the quarter this morning.
First, I would like to take a moment to thank our teams around the world once again for their hard work, incredible resilience and dedication during what continues to be a very uncertain time. The extraordinary people in our factories, warehouses and offices continue to demonstrate tremendous commitment to the health and safety of their coworkers. They are doing this by steadfastly maintaining the safety protocols at work and in their communities. Moreover, the agility of our teams and their ability to navigate, collaborate and manage successfully through the dramatic shifts in our end markets during this period was a true differentiator for us.
During the third quarter, we took advantage of a strong recovery in many markets, following a deep contraction in the second quarter, and importantly, the quarter demonstrated the positive impact that acquisitions have had on our performance. This past quarter saw an acceleration of a recovery that began at the end of the second quarter. The bounce was especially strong with certain of our Class 8 truck, light truck and recreational vehicle customers as well as our plastic packaging customers.
In the Class 8 truck market, our sales rallied as a result of the dual impact of increasing demand and the launch of new mirror programs. According to FTR, an industry research organization, new Class 8 truck preliminary orders exceeded 30,000 in September. That's the highest monthly total since October of 2019.
September bookings for heavy-duty trucks were also 55% higher than in August. Class 8 truck net orders for the last 12 months now stand at a total 197 units -- 197,000 units. We believe that these green shoots suggest that fleets are feeling more confident and that the economy has entered into a period of normalization.
As for the market for recreational vehicles, RVIA, an industry association, estimates that RV manufacturers shipped 42,000 units in September. That's an increase of 31% compared with September of last year. Our RV shipments are expected to surpass 400,000 wholesale units by the end of 2020 and see continued growth into 2021 to more than 500,000 units according to RVIA. Further, our precision packaging business has benefited from a rapid growth of personal care and hygiene products and demand for in-home foods as well as a shift to online shopping in the third quarter, all boosting demand for plastic packaging.
In keeping with our strategy to optimize our portfolio of businesses, we made significant progress in this quarter. First, on August 6, we announced the strategic reorganization of our Eberhard Manufacturing and Illinois Lock businesses. We are proud of the fact that these 2 businesses bring a cumulative 230 years of technical sales, engineering, design and manufacturing experience. This combination will build critical mass with our target markets, deepen our presence with key customers and accelerate growth by integrating the complementary markets and differentiated products into one industry-leading business.
Importantly, this reorganization will also allow us to optimize our manufacturing footprint, streamline our supply chain and capture synergies across our current operations. We expect to and we're still on track to complete the combination by the second quarter of 2021 and believe that the synergies from this combination will contribute significantly to our bottom line in 2021.
Also, on August 11, we closed on the acquisition of Hallink RSB. Hallink is a Canadian-based provider of blow molds and change parts for the food, beverage, health care and chemical industry. As mentioned on our prior call, we were well positioned to leverage our strong cash position and overall stability across our portfolio of businesses to acquire the assets of Hallink. The acquisition of Hallink is an important step in expanding the product offerings, service capability and geographic reach of our Big 3 Precision mold business.
Hallink's complementary products and capabilities offer significant synergies and can create material incremental value through shared know-how and strong relationships across an even broader customer base. We're especially pleased that Hallink's highly committed and talented team had been fully integrated into our operations. Finally, we believe that this acquisition will be accretive to fiscal earnings 2020, and that's before onetime transaction costs.
Turning to the financial highlights for the quarter. Net sales climbed to $65.8 million. That's a sequential increase of 35% compared to the second quarter of 2020 and an increase of 8% compared to the third quarter of 2019. Third quarter 2020 earnings rebounded to $0.48 per diluted share from the second quarter loss of $0.30 per diluted share and more than doubled from the adjusted earnings per diluted share before onetime items in the second quarter of 2020.
Our balance sheet remains strong. In the third quarter of 2020, we generated $9.3 million in cash from operations. Based on our extensive scenario planning, we believe that Eastern's balance sheet has ample resources to navigate the current business environment. As of October 3, 2020, our net leverage ratio is 2.9x and our fixed charge coverage ratio is 2.2x, both well within our bank covenants of 4.25x and 1.25x, respectively.
Although there continues to be uncertainty in the macro environment as a result of the COVID-19 pandemic and the financial impact that measures to respond to it continue to have on Eastern, we are optimistic that a more sustainable recovery is underway. We remain confident that as markets strengthen, we are well positioned to rebound.
I'll turn it over to John to go over the details of our financial results.
