 or “Big, Hairy, Audacious Goal,” lives up to its name — we want to break through the Karman Line. That means climbing 62 miles of KATTCLIMB® ladder rungs into space.

At FIXFAST USA, our BHAG is to sell enough ladders to reach the famous Karman Line. Commonly known as the edge of the Earth’s atmosphere and outer space, the line’s namesake is Theodore von Karman, a Hungarian-American physicist and engineer. Von Karman initially established the boundary at 50 miles in 1957, but the National Oceanic and Atmospheric Administration (NOAA) redefined Karman’s mark at 62 miles decades later. The distance translates into a nicely rounded figure of 100 kilometers above sea level.

Technically speaking, most astrophysicists believe that outer space begins where orbital dynamic forces override the energy of aerodynamic power. In other words, outer space starts where the atmosphere alone does not possess enough force to support a flying vessel traveling at suborbital speeds.

To provide perspective, some of our commercial fold-down ladders range from 7 to 10 feet, while our caged fixed ladders can measure as long as several stories. The 62-mile Karman line equates to roughly 327,360 feet, which translates into more than 30,000 fold-down ladders.

KATTCLIMB® Fixed Ladder Systems

To build enough ladders to get to space, it takes dedication to premium construction. Designing with both user safety and climber comfort in mind, we use the highest-quality lightweight aluminum in our ladder manufacturing process. Aluminum construction means these units are also noncorrosive, allowing for a much longer life span than most steel ladders. Because of the superior construction of our products, our warranties are better than those on many traditional models.

KATTCLIMB® fixed ladder systems come in a variety of configurations and can be used on just about any structure or building. Several of our fixed ladder options include:


In addition to the ladders, we have many mounting options and other accessories available to ensure the highest level of safety. Those options include:
