I'll comment here but this is more for the original comment than yours specifically: Looks like they specifically call out selling structural components (brackets, plates, etc.) pre-assembled with the component, bolts and slot-nut bolted together - loosen the bolts, slide the nut into the slot from one end, and then tighten the bolts. This shows there's likely little opportunity for "pop in" nuts, which can be installed in normal T-slot anywhere along the slot without needing to slide in from an end opening. Also, it looks like the aluminum framing itself is symmetrical, and the bolts are "normal" - the special components and slot-nuts are the components that are asymmetrical. vidanay - not sure what you mean about the "unequal loading to the flanges of the nut" - if I'm understanding you, and their system, correctly, I don't think that's actually an issue. Overall, I think I agree with what others have said - kinda interesting, but if it's more expensive or harder to get than regular t-slot, there don't seem to be enough benefits for _most_ applications. Maybe the strength benefits they claim are enough to justify it for some applications, but honestly if you're depending that much on strength, you'll probably be better off designing a fully custom part. |
