(Comes with tabs + thumbscrews)
Producing castings with perfect surfaces is a difficult task. Our castings are optimized to produce a high quality surface, but even there are often some small imperfections on the machined surfaces. When the products experience a higher number or severity of surface defects we designate them as factory seconds and sell them at a discounted price.
In this case, the square might have the following imperfections: scratches, little holes on the surface or a chipped off piece. See product gallery for reference. Those imperfections don't have a significant impact on performance.
Feel free to ask for photographs of the factory seconds product before shipping.
