If you don't know what this is used for, don't buy it! Diameter can be determined using a thread when flaccid and laying out on a ruler.
This model has a diameter of 30 mm and 5 mm spikes, so it fits for 28-32 mm range. If you need other diameter, just text me, and I will provide a custom model. Have fun!
Padlock not included! You can order them here:
