WENKO 17794100 Power-Loc corner shelf Bovino Small - Attach without drilling, Easy Hang On, stainless steel, 26 x 4 x 18 cm, glossy (household goods) 5
After the third shower rod with holders had to be replaced due to rust, had to be something else. Due to the product reviews, I opted for the system of Wenko.
The price is relatively high, but convinced the system. After drying time of 24 hours, the corner shelf holds (tested with two children) bombproof. She looks also very fancy and for the previous two months, no rust!
