This is a Blackline cat tree component from RHR Pets. This sisal pole has 5 M10 screw holes at the bottom and 1 at the top, a 20 cm diameter, and is 40 cm long. You can mount the sisal pole on any RHR Pets cat tree provided the original has the same thickness and screw size. The sisal is glued to the sisal pole and has an ABS interior, which makes it extra strong.
