General instructions:

When entering a competitor part number, begin entering one number or character at a time, including required dashes or spaces…this will automatically begin a drop down listing of any competitor numbers available for cross referencing to A.Y. McDonald. If nothing displays in the search box as you enter characters, reduce the number of characters starting from the last character entered. If still nothing appears, the number you are searching for is not in the database and should be verified by other means. Note: Sizes may or may not be included in a competitor’s part number. Always verify size requirements. If you see (-ALT) after a competitors model number and size, that tells you there is a difference in the McDonald crossover versus the competitors model, i.e. (-ALT-TFT). Contact A.Y. McDonald Customer Service at 1-800-292-2737 for clarification or more information.
