Business and Credit Concentrations	9 Months Ended
Business and Credit Concentrations	Sep. 30, 2018
Risks and Uncertainties [Abstract]
Business and Credit Concentrations	Business and Credit Concentrations Concentrations of risk with respect to trade accounts receivable are generally limited due to the large number of customers and their dispersion across several geographic areas. Although the Company does not foresee that credit risk associated with these receivables will deviate from historical experience, repayment is dependent upon the financial stability of those individual customers. The Company establishes allowances for potential bad debts and evaluates, on a monthly basis, the adequacy of those reserves based upon historical experience and its expectations for future collectability concerns. The Company performs ongoing credit evaluations of the financial condition of its customers and generally does not require collateral. No single customer accounted for 10% or more of the Company's consolidated net sales for three and nine months ended September 30, 2018 or 2017 or accounts receivable at September 30, 2018 or December 31, 2017. Certain components from third parties used in the Company’s products are procured from single sources of supply. The failure of a supplier, including a subcontractor, to deliver on schedule could delay or interrupt the Company’s delivery of products and thereby materially adversely affect the Company’s revenues and operating results.
