Warranty expense rate description			Our warranty expense rate in the three months ended July 2, 2022 is a result of a decrease in the use of higher-cost contract labor we had used in the first quarter of 2022 to respond to warranty claims due to a currently tight labor market, whereas in the three months ended July 3, 2021, the wind-down of certain commercial business in the first quarter of 2021 resulted in warranty costs higher than those we would incur in the normal course of business.During the six months ended July 2, 2022, we recorded warranty expense at a rate of approximately 2.1% of sales, which was about level with the six months ended July 3, 2021 of 2.2% of sales.
