Model
The drain cover protects your drain from clogging up. The cover is made to fit over different size drains, from a small sink to a shower or bath. I use mine while washing my long haired dachshund in the bath, to make sure it won't clog my drain. The flexibility of TPU makes sure there aren't any gaps on the sides . I haven't tried it in other materials.
Measurements
The diameter of the model is 120mm with a maximum thickness of 2,5mm. The holes within the cover have a diameter of 4mm to let water through, but blocking most of the hairs or other stuff you wouldn't want in your drain.
