I bought these brackets to be able to mount a Festool MFT-style top to my mitre saw stand. So far this has worked out well. The brackets grip the rails of the stand very firmly and, once locked down they resist a lot of leverage…the whole stand will tip over before the brackets come loose. That said, the top comes off easily when the clamps are released. The brackets are very competitively priced and have suited my purpose very well (not exactly what they were designed for) and I am very happy with them. Recommended.
