Your leak rope sensor's running but it stops short of that far corner where the A/C condensate line drips. You need another 20 ft without buying a whole new sensor. This APC NetBotz leak rope extension bolts straight onto your NBES0308 and extends your detection coverage along the same continuous run. Cable ties included for clean routing. No reconfiguration, no new appliance. Just plug it in, lay the rope where you need it, and your NetBotz dashboard now covers the full length. Requires an existing NBES0308 sensor – this is the extension, not a standalone unit. Operating range 0–45 °C, 0–95 % humidity. Usually ships within 2 weeks
