Product Warranties Disclosures [Abstract]

WARRANTY LIABILITY

WARRANTY LIABILITYCPP and HBP offer warranties against product defects for periods generally ranging from one to ten years, with limited lifetime warranties on certain door models. Typical warranties require CPP and HBP to repair or replace the defective products during the warranty period at no cost to the customer. At the time revenue is recognized, Griffon records a liability for warranty costs, estimated based on historical experience, and periodically assesses its warranty obligations and adjusts the liability as necessary. CPP offers an express limited warranty for a period of ninety days on all products from the date of the original purchase unless otherwise stated on the product or packaging from the date of original purchase.
