All spec.dock models are designed to accept Apple Universal Dock Inserts, allowing multiple iPod and iPhone models to be used in the same spec.dock. By switching out these interchangeable inserts, any dockable iPod or iPhone model can be used in your spec.dock with identical functionality.

All spec.dock packages come with one insert included. Only add this product to your cart if you wish to have additional inserts for iPod or iPhone models other than the one you specified in your order.
