Freight Orders

Freight deliveries require a delivery time be scheduled and someone must be present at the time of delivery to inspect and sign for the merchandise. A representative from the freight carrier will call the phone number entered at checkout to schedule the delivery.

Liftgate Service

For freight deliveries, you have the option of adding a liftgate to your delivery. A liftgate is the device that lowers a product from the truck to ground level.

CPO recommends adding liftgate service for freight deliveries exceeding 100 lbs if you do not have a loading dock or fork lift at the delivery address. Additional charges may apply. The liftgate option will be presented during the checkout process.

Please note that liftgate service only ensures the product is removed from the truck. We recommend you have the additional help of two to four people to move the product to its desired location because drivers are not required to assist.

Requesting liftgate service after ordering may result in additional charges and delays.
