The 15mm x 30mm profile of the Extrusion has slots on on all four sides that accept standard M3 hardware. Rather than using a T-nut, which is more expensive, slide a M3 hex head screw along the slot and adjust brackets and other build materials as needed. As illustrated in the image above, the ends of the Extrusion also have a 5mm hole pitch that can be M3 tappped. The 15mm x 30mm Extrusion has one slot on each 15mm face and 3 slots on each 30mm face, allowing for some additional design flexibility when compared to the standard 15mm extrusion.

The 15mm x 30mm Extrusion is great for areas where more torsional strength is needed in an application than the standard 15mm Extrusion.
Torsional Strength is a measure of the ability of a material to withstand a twisting load.

The point of the extrusion system is to offer more flexibility in design than would come in a fixed pitch system. The slots in the extrusion allow brackets and other components to be slid along the 15mm Extrusion to an infinite number of positions.
