Income Tax [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. The tax years prior to our fiscal year ended April 3, 2016 are closed to examination by the Internal Revenue Service. Our federal tax return filed for our fiscal year ended March 29, 2015 was examined by the Internal Revenue Service with no adjustments. For state and local income tax jurisdictions, the tax years prior to our fiscal year ended March 30, 2014 are closed to examination, with few exceptions. Our effective tax rate was 38.5% for the six months ended October 1, 2017 compared to 38.1% for the six months ended October 2, 2016. As of October 1, 2017 and April 2, 2017, our balance sheet included a long-term liability for uncertain tax positions of $0.2 million and $0.8 million, respectively, which arose from tax positions taken by Stauber on its tax returns for periods prior to our acquisition, offset by a corresponding long-term receivable as the Stauber acquisition agreement provides us with indemnification by the prior owners for any tax liabilities relating to pre-acquisition tax returns. Accordingly, we have also recorded an offsetting, long-term receivable for $0.2 million and $0.8 million as of October 1, 2017 and April 2, 2017, respectively, and, as such, any change in the unrecognized tax benefit will not impact our effective tax rate in future periods. We expect these uncertain income tax amounts to decrease as the applicable examination periods by the relevant taxing authorities expire.
