Sink without screw holes

Washbasins with stud bolts and also 1m or larger only hold at two points or do you have supports underneath them :)

No, but the basin fits perfectly on the wall and between the nut and the basin there is still a large metal plate for a properly large support surface. At least with my washbasin. When I compare my double washbasin with these two hooks, which rather take the load at a point instead of pressing the entire basin against the wall over a large area... yes, then I have slight concerns. But I did say explicitly that this is a gut feeling because I have no experience with washbasins. I only know my own basins.

Washbasins with stud bolts and also 1m or larger only hold at two points or do you have supports underneath.

Of course, there is a support underneath, it's called a cabinet :D Of course hung on the wall :p

Hi, they should actually hold, I learned GWS back in the late 70s. There were still one or two brackets, either the tabs, alternatively there were also such consoles made of cast iron. Just enter this item number on EBAY: 254191332504 Regards Olli

What kind of profession is GWS? :-)

What kind of job is GWS? :)

Gas-water-"miscellaneous".....

Gas, water sh...
Near Hanover there is a plumbing company that has the slogan: "Gas, water, sh...iny bathrooms" on their company cars.

By the way:
Very important! Tighten the screws/nuts very carefully, never "bang" them tight.
Back then, not only did a sink break, there was always nagging from the foreman.
