Revenue from Contract with Customer [Abstract]  
Revenue Revenue
Revenue from products or services provided to customers over time accounted for 27.9% and 25.1% of revenue for the three months ended June 30, 2021 and 2020, respectively, and 26.8% and 25.9% of revenue for the six months ended June 30, 2021 and 2020, respectively. The majority of revenue under these long-term agreements is recognized over time either using an input measure based upon the proportion of actual costs incurred to estimated total project costs or an input measure based upon actual labor costs as a percentage of estimated total labor costs, depending upon which measure the Company believes best depicts its performance to date under the terms of the contract. Revenue recognized over time using an input measure was $27,687 and $24,858 for the three months ended June 30, 2021 and 2020, respectively, and $48,795 and $49,290 for the six months ended June 30, 2021 and 2020, respectively. A certain portion of the Company’s revenue recognized over time under these long-term agreements is recognized using an output method, specifically units delivered, based upon certain customer acceptance and delivery requirements. Revenue recognized over time using an output measure was $15,487 and $10,688 for the three months ended June 30, 2021 and 2020, respectively, and was $23,751 and $19,033 for the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021 and December 31, 2020, the Company had contract assets of $40,496 and $37,843, respectively, that were recorded in “Inventories - net” within the Condensed Consolidated Balance Sheets. As of June 30, 2021 and December 31, 2020, the Company had contract liabilities of $6,098 and $1,324, respectively, that were recorded in “Deferred revenue” within the Condensed Consolidated Balance Sheets.

The majority of the Company’s revenue is from products transferred and services rendered to customers at a point in time. Point in time revenue accounted for 72.1% and 74.9% of revenue for the three months ended June 30, 2021 and 2020, respectively, and 73.2% and 74.1% of revenue for the six months ended June 30, 2021 and 2020, respectively. The Company recognizes revenue at the point in time at which the customer obtains control of the product or service, which is generally when the product title passes to the customer upon shipment or the service has been rendered to the customer. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at a physical location.

The following table summarizes the Company’s net sales by major product and service category for the periods presented:
