Precautions when assembling
*For safety, the rack should always be assembled by two or more people.
*When assembling, iron sand may come out from inside the frame. This is due to particles used in the pre-painting process entering through holes in the frame, and does not pose any danger when used. If any iron sand remains inside the frame, please remove it from the holes in the frame before assembling.
*The rack comes with paper assembly instructions. *The assembly instructions are in a sealed bag labeled "Delivery Note" and are attached to the outside of the box.
* Assemble the bolts in a partially tightened state, and then tighten them completely after everything is assembled. By doing so, you can assemble the rack in a shape that matches the shape of the base. If you assemble the rack by fully tightening the bolts of each part from the beginning, the rack and base may not match after completion, resulting in wobbling. If wobbling occurs, loosen all the bolts and then retighten them.
*When tightening the bolts, tightening them too much may cause deformation of the frame. Please be careful not to tighten the bolts so much that it deforms the frame. (When tightening the bolts and nuts that directly attach to the frame, only tighten them to the point where the frame bends 1-2 mm. If it bends only slightly, loosen the bolts and the elasticity of the metal will allow it to return to its original shape.)
Please be careful not to overtighten the bolts attached to the top end of the support posts, especially the red circle in the image below, as this may cause the end of the support post to deform. MBC original racks use anti-loosening nuts, so there is no need to tighten the bolts with enough force to deform the support posts. Be careful not to overtighten the bolts, especially when assembling using an impact wrench. 
*The 148cm base has a front and back, so please be careful not to confuse the front and back.
*The poles have numbers engraved on one side. For squat stands and half racks, the side with the numbers should be facing forward. For power racks, the numbers should generally face the inside of the rack, but if you are using J-cups or safety arms on the outside of the rack, face them in the direction that is easiest to use.
Tools required for assembling the MBC original rack
- 1 pair of 30mm wrenches or spanners
- 1 pair of 19mm wrenches or spanners
・Stepladder (or large footstool) 1 unit
*Tools required for installing the strap safety
1 pair of 6mm hex wrenches
Please prepare your own tools.
Assembly flow
The assembly of MBC original racks, squat stands, half racks and power racks,
① Assembling both side parts
↓
② Connect the assembled sides and attach the triangular plate
↓
③Installation of J-cups, safety, plate storage, etc.
The process is as follows.
Assembly process 1: Assembling the side parts
①First, assemble the bottom part of the side. 
The base of the half rack has a front and a back, and the slightly longer side is the back side of the rack. Please be careful not to confuse the front and back. 
Only in this part do you use a thin bolt. Insert it from below to secure the support and base. This part cannot be fully tightened after assembly, so please tighten it firmly at this point. 
② Next, assemble the upper part of the side part. If you are attaching a nameplate, fix it with the bolts at this stage. 
From this point onwards, all assembly steps will use the thicker bolts. 
Assembly process 2: Connecting both sides, attaching the triangular plate, and attaching various parts. 
③ Stand both assembled sides upright and connect the tops with the chinning bar. When doing this, be sure to use a sturdy stepladder or footstool and have multiple people work together. (The shape of the chinning bar on the current half rack is different from the one in the photo.) 
④Connect the lower part and attach the triangular plates to the side columns and the rear and center columns.
* When installing a plate-loaded lat pulldown/low row attachment, please install the horizontal post three holes forward. 
⑥ Attach the sandwich J-cup and safety and you're done.
