Availability:

RAM Mounts supply is pretty good in Australia, but they have thousands of parts so we can't stock them all on our shelves. If our site shows this item as in stock in our warehouse (see above), great! It will ship immediately from our warehouse. If it shows as Pre-Order, we get fortnightly shipments from RAM Mounts and our site should show if it's in stock in Australia.

• If in stock in Australia we can have it in about a week or less
• If it's not in stock in Australia, unfortunately the ETA can be quite long, as RAM Mounts in the USA have a manufacturing lead time of 6-8 weeks. But if you'd like to contact us we can find out a more accurate ETA for you
