Discover exactly what parts come in the eitech Supplementary Bag 2-9 holes, how to use them to expand your builds, and which projects benefit most from these metal plates and bars.
Quick answer
The eitech Supplementary Bag 2-9 holes contains 51 pieces of flat bars, curved bars, and plates with 2 to 9 holes, designed to add structural support and new shapes to any eitech metal construction kit.
Why you might need this supplementary bag
If you have a basic eitech set and want to build larger or more detailed models, standard parts often run short. This bag fills gaps in flat bars and plates, letting you extend frames, reinforce joints, or create flat surfaces without buying a whole new kit.
Limitations to keep in mind
This bag only contains bars and plates with 2-9 holes. It does not include gears, axles, wheels, or specialty connectors. If your project needs moving parts or angled brackets, you will need other supplementary sets or your original kit's pieces.
Frequently asked questions
- What exactly is in the bag?
- The bag contains 37 pieces of flat and curved flat bars with 2-9 holes, plus 14 pieces of plates and trapezoidal plates ranging from 2x2 to 9x5 holes. That is 51 pieces total.
- Which eitech kits is this bag compatible with?
- It is designed as a supplement for all eitech metal construction kits. The hole spacing matches standard eitech parts, so you can mix them freely with any set you already own. Check your current kit's inventory: if you have fewer than 10 flat bars or plates, this bag will significantly expand your building options.
- How should I use these parts in a build?
- Use the flat bars to create longer frames or cross-braces. Use the plates as solid base platforms, roof surfaces, or side panels. The curved bars help form rounded edges or wheel arches. Start by replacing temporary single-hole connectors with these longer pieces for a stiffer structure.
