Mockups For Free is a free-resource site offering PSD mockups and design files aimed at graphic and web designers.
A straightforward, no-signup source for device and product mockups when you need something quickly without navigating a larger, more cluttered aggregator.
Good for quick, low-stakes mockup needs (portfolio presentation, internal review decks), rather than a primary resource for client-facing final delivery.
As a smaller aggregator, the catalog is less deep than the bigger sites in this category (Freebiesbug, UI4free): worth checking those too if you don't find what you need here.
