劍麻柱 20吋 x 5吋Ø - M8（黑線）

The 5 inch diameter is a perfect match for the rest of my setup, and my cat took to it immediately. Screwing it on was simple since the M8 holes lined up with the top and bottom of the old pole, and the sisal feels dense enough to actually last.

I measured the old post before ordering and this 20 inch one slid right in with both M8 screws catching on the first turn. The 5 inch diameter matches my existing platforms, so the cats didn't even notice the swap. Scratching post looks sturdier than the worn one it replaced.

The M8 holes at both ends lined up perfectly with the old base, so swapping out the worn pole took me maybe five minutes. My cat was scratching on it before I'd even finished tightening the top screw. Solid sisal wrap too, hardly any loose fibers.
