Free shipping to every address in the contiguous United States.
Order by 10am Pacific, Monday to Friday, and in-stock items ship the same day. Orders placed after the cutoff ship the next business day. Need it sooner? Contact us before ordering and we can arrange express delivery.
Smaller items — parts, accessories, strap and film — ship by UPS or FedEx with tracking. Large machines ship by freight on a pallet, and liftgate service is included at no extra charge: the driver lowers the shipment to ground level, so no loading dock or forklift is needed on your end.
Someone needs to be available to receive and sign for a freight delivery. Inspect the shipment for visible damage and note it on the delivery receipt before signing.
Alaska, Hawaii, U.S. territories and international addresses are quoted separately — email support@rockcub.com before ordering.
Rockcub machines carry a 1-year warranty, handled by our U.S. team rather than an overseas queue.
Returns are accepted within 30 days of delivery. If an item arrives defective, damaged or not as described, we arrange a free return and a full refund — no return shipping, no restocking fee. Other returns need the item unused and in its original packaging; return shipping and a 15% restocking fee apply.
Email support@rockcub.com with your order number to start either.
