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. Three interfaces are cut to a named size: the Neptune OS-1 body, an M16 threaded float switch, and an M10 threaded float switch. 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.

ATO mount questions, answered straight.
Which sensors have a bracket made for them?
Three interfaces: the Neptune OS-1 body, an M16 threaded float switch, and an M10 threaded float switch. Everything else takes the universal bracket, which holds a range of sizes.
How do I mount the bracket, hang it or screw it?
Hang one over the tank or sump wall, or screw one to a cabinet wall. Pick whichever matches where you want the sensor.
What if my sensor is not the Neptune OS-1 or an M16 or M10 float switch?
Each product page names the popular sensors that do not fit, so start with that list. Anything else goes on the universal bracket, which grips a range of body sizes.
Can I adjust the height once the bracket is mounted?
Yes. Every bracket has real travel built in, so the sensor is not stuck at one fixed spot.
Does the bracket stop my tank from overflowing?
No. These are brackets, and we make no claim about flood prevention. They hold a sensor in place.
