Welcome to Flotron – Designer and Manufacturer of Rotation Fixtures

Flotron designs and manufactures mechanical ground support equipment (MGSE) and engineered aerospace tooling solutions. Flotron offers an off-the-shelf catalog product line of rotational holding fixtures (rotation fixtures) to support ergonomic assembly, integration, test, finish operations, transportation, among other manufacturing processes. We provide engineered solutions that consider safety factors and stability criteria and are trusted to support the highest value hardware.

Rotation Fixtures


Flotron’s off-the-shelf product line of rotation fixtures ranges from a 50 lbs capacity bench top assembly fixture to a 14,500 lbs capacity motorized spacecraft positioner with swing radii up to 88 inches.

Modified Standards

In cases where Flotron can utilize an off-the-shelf product as a starting point and make a few simple modifications to meet our customer’s requirements, we identify these turnover fixtures as Modified Standards.

Custom Solutions

For special requirements that cannot be resolved with an off-the-shelf or Modified Standard Flotron, our experienced team of engineers will work with you to design a custom solution.


Flotron's Circuit Card Extractors and Insertion tools are self-guided, ergonomic solutions for removing from or installing into an electronics chassis while minimizing the potential for circuit card assembly (CCA) damage. Submit a completed Extractor Design Sheet and our sales engineers will design a tool for your specific application.
