    Equipment Arrival

    Shipping times are not guaranteed and may vary by address. Upon delivery, inspect each item and match the count with the delivery receipt before signing. Report any missing or incorrect items within 24 hours; claims reported after this period may be denied. Inspect items for damage in front of the driver before signing the receipt.

    How Do I Handle a Damaged Shipment?

    If any items are damaged, mark the receipt as “Damaged,” specifying the items and the nature of the damage. Refuse only the damaged items, keep and sign for the rest, and clearly note the refused items on the receipt. Contact our Customer Service to report which items were refused and which were accepted. We will ship replacements once our Shipping Department confirms the damage with the Freight LTL Company. If you sign for the delivery but later discover damage, you are responsible for it. You will need to contact the Freight LTL Company’s claims department directly to file a claim.
