This is designed to be used with most sinks and will extend much further than the stone bridge we also carry. It can hold a static load of up to 10kg, which makes it strong enough for pretty much any stone you want to put on there (the maximum load while sharpening is slightly less than the static maximum load, but is still more than strong enough for normal sharpening needs). The bridge also comes with rubber feet, which allow it to be used as a stand-alone stone base. It will fit sinks with inner dimensions from 370-625mm. We also recommend using a stone holder (like our large stone holder) in conjunction with the sink bridge.
