Thanks, David. Turning to our outlook on Slide 9. We are raising our outlook for net sales, adjusted EBITDA and adjusted EPS for the fiscal year based upon the better-than-expected results we experienced in Q2, as well we expect the back half of the year to unfold. Our third quarter 2021 outlook is for net sales to be up approximately 80% to 100%, and adjusted EBITDA to be in the range of $200 million to $220 million. In addition, we expect to grow our adjusted EPS, up to $2.80 to $3.10. For FY '21, we now expect our net sales to be up approximately 40% to 50%, and adjusted EBITDA to be in the range of $700 million to $750 million, which is up $260 million to $290 million versus our prior estimate. In addition, we expect our adjusted EPS will be in the range of $10 to $10.70. As evidenced by the results we delivered through Q2, we are successfully navigating this continued period of unusual supply-demand dynamics. As we've touched previously, by optimizing our supply chain, we are able to not only serve our customers reliably, but we're able to do so with shorter lead time than others. That's a direct credit to the sustained efficiency of the Atkore Business System. This high-demand paired with constrained supply in PVC and other categories is creating a very favorable pricing environment that is ultimately driving significant value and outperformance in our results. That said, in the long term, we do not expect this level of industry-wide supply constraints to be the new normal. To date, in the third quarter, though, we are continuing to see strong PVC conduit demand and an elevated pricing environment. This is partially due to our ability to manage the market supply constraints that resulted from the Texas winter storms. Moving to Slide 10. I want to take a moment and reflect on the tremendous growth of the business over the past several years and frame our recent results and outperformance. You'll recall last quarter, in addition to giving our guidance for FY '21, we also provided some additional early perspective on FY '22. While we caution that we would not be making a habit of providing long-term guidance, we do want to communicate today our latest perspective has increased from what we outlined for you on our last call. While we continue to expect more normal historical levels in PVC demand and pricing, as well as other parts of the businesses we approach the late fall and winter months, we have adjusted our expectations for FY '22. We are now providing a range for adjusted EBITDA of $400 million to $450 million. As you can see here in this chart, over the FY '15 to FY '20 time period, we delivered a strong CAGR of approximately 15%, a growth rate that we're really proud of, especially as the market backdrop has varied across these years. Looking forward at our early perspective for adjusted EBITDA in FY '22, while the level of EBITDA is down from the record we expect to achieve in FY '21, the growth rate is still in line with our historic double-digit growth rate when compared to FY '20. Before we turn to Q&A, I just want to reiterate that we had a great first half of the year, but we are even more excited about what the future holds for this tremendous company. With that, we'll turn it to the operator to open the line for questions.
