I suggest going to the Digital Deck Covers website and viewing the photos accompanying the various options available. Also, there are several photos posted by satisfied customers.
My experience is they fit snugly but are manufactured to easily be removed and placed. The dust cover dimensions are tailored specifically to fit your equipment or the measurements you provide. Based on my experience with the Yamaha, Onkyo and PrimaLuna covers I received, they are not a one size fits all product.
I strongly encourage you to double check your measurements before placing an order. Also think about your preference for an open versus closed dust cover fit. I opted for an open back to accommodate interconnects, since all of my audio systems are in use on a daily basis. If you wish to have a dust cover for equipment long term storage, you may want a snug fit in the back. Finally, do not hesitate to contact Courtney if you have questions or need suggestions based on your equipment surfaces.
