We have been selling flyracks for years, and in 2023 we decided it was time to bring years of learning to the design table. These racks are our most durable, functional, and lightweight flyracks to date. 

Housed in our everything-proof 54L Polyproof, your rack gear is protected from water, dust, shock, and that rough guy out back of the luggage carousel. Complete with a long handle and wheels, you are ready to roll from gig to gig. 

We make our internal flyrack from premium birch plywood. It's lightweight and engineered to be robust all on its own. The robust rack frame structure is reinforced by itself and does not rack when empty. 

Front and rear rack rails are adjustable even when the rack is fully loaded, allowing you to refine your perfect rack depth. Passive cooling is designed into the rack, and these slots also make cable management a breeze with the addition of velcro or zip ties. 

The number one request we got for flyracks over the years was a home for a laptop.

Especially when deployed at a gig. So we created a laptop cradle designed to fit a 16-inch Macbook Pro which sits on top of the rack. It can also be used as a shock-isolated home for a laptop inside the 54L Polyproof. The laptop cradle is removable to allow for easy top-down access to the rack unit for installation. 

Roll into a gig, easily lift out the flyrack with ergonomically positioned handles, close the lid of the 54L Polyproof, and sit the flyrack on top. The feet are designed to locate the flyrack to the top side of the case. They also provide shock isolation from stage and riser vibration. 

Need more than one rack?

Easily stack one on top of another with the feet again aligning to position the stack. 

The flyrack is shock-isolated within the case when traveling. It will pin down safely with or without the laptop cradle in case.

Our uber-lightweight Fiasco Flyracks are ready to depart to any destination. Designed for no-nonsense touring audio engineers and musicians. A welterweight champ, it's light on its feet but built to take the big hits. Roll through every terminal with ease.

Price includes: Fiasco Flyrack 4U, 16in Macbook laptop cradle & Polyproof 54L.
