The T-Slot Extruded Aluminum frame features proprietary designed mounting fixtures and a custom seat track for the mounting plate, weighing 7.826 pounds without fasteners and 8.636 pounds with them. This flexible system allows short bars to be moved along upper and lower rails for various mounting plates, accommodating future experiments. Cameras and other equipment can also be mounted on the T-Slot rails, which are strong enough for crew restraints if needed. The open volume between the plate and rack accommodations provides full access to the experiment and allows for electrical/data cable routing. Additional rack-mounted drawers can be accessed up to 8 inches forward of the Express racks. Assembled on Earth with attached seat track, the EAS fixtures and fittings are bolted together using 12.9 Hi tensile metric fasteners. On-orbit assembly is simple: unfold and attach upper and lower main rails to the ISS seat track, slide T-Bars to central positions, tighten fasteners on long rails, and finally, attach the mounting plate using the seat track. FOS analysis confirms components within limits, including bolt failure analysis. FEA reports with moment data are attached, along with a draft SIDD requiring further work if accepted. eDrawings 3D files show folded vs assembled configurations, offering measurement capabilities for optimal viewing.
