为什么sliding door 的轮子在门的上部会比较容易推动?
轮子在门的上部会比较容易推动(和在下部比起来)
for what i guess, door hanging from top there are no much contact to the bottom side ( just a guide, but there a not much friction)
but if u put the roller bottom, the door will mount on the guide, and it will cause the friction lo.....
so normaly the sliding door with up and down roller or bottom with roller nia....
am i right??? |
