Equity Valuation Assumption Difference, Footnote [Text Block] | In recomputing the fair value of equity awards, the Company used the same methodology as that which was used to initially determine fair value for financial reporting purposes. The fair value of stock options was determined using a Black-Scholes option pricing model. The fair value of PSUs was determined using either the Company’s closing stock price as of the applicable date, or a Monte Carlo simulation model, as applicable. The fair value of restricted stock was determined using the Company’s closing stock price as of the applicable date. The primary driver of the increase in fair value of outstanding equity awards from the amounts initially reported in the Summary Compensation Table was the increase in the Company’s stock price. |  |  |
Compensation Actually Paid vs. Total Shareholder Return [Text Block] | On an enterprise level, we set aggressive performance metrics for performance awards. Over the three-year period from 2021 to 2023, our total stockholder return was 137%, which represents a 108% higher return than that of the S&P 600 Capital Goods Index over the same period. As a result, consistent with our pay-for-performance philosophy, the PSUs initially granted to NEOs in 2021, which were tied to the same three-year period, were earned at 132% of target in 2023. •The following graph compares the cumulative total return to stockholders of the Company’s common stock relative to the cumulative total return of the S&P 600 Capital Goods Index over the four-year period from 2020 to 2023. The graph assumes that the value of the investment in the Company’s common stock, and in each index, was $100 on December 31, 2019 and assumes reinvestment of all dividends through December 31, 2023: |  |  |
Compensation Actually Paid vs. Net Income [Text Block] | Although Net income and the relationship between Net income and compensation actually paid are disclosed herein, we do not use Net income as a financial-based metric in determining compensation levels or incentive plan payouts. Over the four-year period from 2020 to 2023, compensation actually paid to our PEO and the average compensation paid to non-PEO NEOs have generally aligned with the changes in our key financial performance metrics, as indicated in the graph below: |  |  |
Tabular List [Table Text Block] |
Adjusted income before income taxes* | Used as a key financial metric in the Company’s STIP program for 2023 (representing 60% of each NEOs’ total bonus opportunity); calculated by taking GAAP income before income taxes and adjusting for any unusual or nonrecurring items that were not contemplated in the annual target setting process (i.e., acquisition and integration-related expenses, environmental charges of a discontinued operation and purchase accounting effects in 2023).
Adjusted EBITDA margin* | Used as a key financial metric in the Company’s STIP program for 2023 (representing 20% of each NEOs’ total bonus opportunity); calculated by taking the sum of GAAP net income, interest expense, depreciation and amortization expense, other income/expense, income tax expense/benefit and any unusual or nonrecurring items that were not contemplated in the annual target setting process (i.e., acquisition and integration-related expenses and purchase accounting effects in 2023), and dividing the total by net sales for the applicable period. Important metric when communicating with investors and other key stakeholders.
Adjusted earnings per share (“EPS”)* | Calculated by taking GAAP net income, adjusted for any unusual or nonrecurring items that were not contemplated in the annual target setting process (i.e., acquisition and integration-related expenses, environmental charges of a discontinued operation and purchase accounting effects in 2023), and dividing the total by the weighted average diluted shares outstanding for the applicable period. Used as a key financial metric in NEOs’ LTIP awards, where 75% of the financial target is based on cumulative EPS over the applicable three-year performance period.
Return on invested capital (“ROIC”)* | Calculated as net operating profit after taxes, divided by total invested capital for the applicable period. Used as a key financial metric in NEOs’ LTIP awards, where 25% of the financial target is based on average ROIC over the applicable three-year performance period.
Total Shareholder Return Amount | $ 247,000,000 | 148,000,000 | 137,000,000 | 104,000,000
Peer Group Total Shareholder Return Amount | 192,000,000 | 139,000,000 | 145,000,000 | 116,000,000
Net Income (Loss) | $ 157,400,000 | $ 120,400,000 | $ 100,600,000 | $ 96,200,000
Company Selected Measure Amount | 204,900,000 | 150,500,000 | 128,000,000.0 | 133,300,000
Additional 402(v) Disclosure [Text Block] | For the year ended December 31, 2023, the Company generated adjusted income before income taxes of $204.9 million, which was $37.3 million, or 22%, ahead of the target for the year set for annual cash-based incentive purposes, and $19.7 million, or 11%, above the maximum payout level. On a year-over-year basis, the adjusted income before income taxes generated by the Company was up $54.4 million, or 36%. As a result, each of our NEOs earned 200% of target under the Earnings component of the 2023 STIP. For the year ended December 31, 2023, the Company generated an adjusted EBITDA margin of 16.6%, which was 180 basis points ahead of the target for the year set for annual cash-based incentive purposes, and 60 basis points above the 16.0% required to achieve the maximum payout level. On a year-over-year basis, the adjusted EBITDA margin generated by the Company was up 160 basis points. As a result, each of our NEOs earned 200% of target under the EBITDA margin component of the 2023 STIP. In recognition for their contributions to the Company during 2023, and performance against their individual objectives for the year, each of our NEOs earned the maximum level of achievement under the individual objective component of the 2023 STIP. |  |  |
