主軸擴張套筒 / 門把手 / 5-8 mm

Slid right onto my 6mm spindle without any wobble, and the plastic is much more forgiving than I expected when tightening the grub screw. Exactly what I needed to bridge that small gap in my handle.

Slipped over the 6 mm spindle without any fuss, and the 5–8 mm range means it’ll work for whatever handle I swap in later. The plastic feels solid enough that I don’t worry about it cracking under daily use.

Was a bit unsure about plastic sleeves, but these fit snugly around the 6mm spindle I’ve got, and the door handle doesn’t wobble at all now. Took two minutes to pop them in, and the 5–8mm range gives decent room for adjustment.
