Please note: custom sizes can only be ordered over the phone at 1-877-771-8277. Shipping cannot be calculated directly through the site. For a shipping quote, please use the contact email button on the upper right and let us know the size, ounce weight (9, 13, 17 or 20), quantity and ship-to zip code. The majority of custom sizes are too heavy for FedEx Ground and will ship on a pallet through a common freight carrier. Thanks.
