How to Read FW Murphy Serial Numbers & Date Codes

Most FW Murphy products have a 2-year repair or replace warranty. To determine if your FW Murphy product lies within the warranty period, you need to determine when your product was manufactured.

The key to the manufacture date is in the serial number on the product label (the product label must be attached to the product in order to file a warranty claim). This page explains how to read an FW Murphy serial number & date code.
