These appear well made and did the job very efficiently. These brackets are not very heavy guage metal and so careful thoight should be given to the amount of weight that they will be expected to support.
The new design is made in 3 parts but the lowest section just was too tight to fit between the bowls. The problem was solved by removing the lowest section and combining the upper 2 parts with the original lowest section. The upper oblong seal has been improved significantly. Franke could much improve the design if the lowest vertical section was oval and similar to the top red section The final combined (old & new) overflow works very well.
