ATO Sensor Mounts
Brackets that hold an ATO sensor or a threaded float switch at the height you set. Built for the Neptune OS-1 and for M16 and M10 float switches.
An auto top off sensor only works where you put it, so every bracket here has real travel built in. Hang one over the tank or sump wall, or screw one to a cabinet wall. Only three interfaces get a hard size from us: the Neptune OS-1 body, an M16 threaded float switch, and an M10 threaded float switch. Everything else is a measure yours first part. Each product page names the popular sensors that do not fit, so you do not buy the wrong one. These are brackets, and we make no claim about flood prevention.
