1Q: Is three-dimensional bracket the only choice to connect three profiles from different directions?

A: Not really, beside multi-dimensional bracket, struct profiles from three directions could also be connected with anchor joint, bolt connector, die cast bracket etc.

2Q: What is the difference between multi-dimensional corner bracket and other connection type?

A: As shown in the product image, the corner connected with three dimensional connector is spherical and could be protected with an ABS cap. With other joining kits, the multi-dimensional connecting of profiles could be realized as well, but shown as a right-angle corner. If you prefer a round corner appearance, we will recommend multi-dimensional connector together with R90 strut profiles for the outermost corner.

3Q: Is any further machining process needed to build the frame after we receive the components?

A: In addition to the products, we are also offering a variety of services including machining and pre-assembly. Please let us know your requirements or send us the design drawing (the official software we use is Solidworks). All the machining could be done in our workshop, what you need for assembling is just a matching wrench (available on request), drawing of frame and a little bit patience.
