Wiska Indubox 818A — IP65 Blank Enclosure (215x200x140mm)
Basic style enclosure without a window. Made from polycarbonate, so it's easy to cut and drill on site — a great choice for a quick first-fix or retrofit.
Versatile:
- Flush mounting of components to the front face, including temperature controllers, thermostats and metering devices
- Internal DIN rail installation for breakers, terminals and other rail-mounted parts (DIN rail not included, sold separately)
- Also works as a straightforward IP65 terminal/junction box when extending or modifying existing wiring
Confirmed fascia fit:
- Novus N1040 and N1050 PID temperature controllers (standard depth)
- Novus N322 digital thermostat — both the PT100 and J/K/T thermocouple (N322-JKT) input versions
- Also suitable for most other panel-mount PID controllers and refrigeration thermostats of similar DIN size
Includes multiple glanding/entry points with pre-marked drilling points.

Frequently Asked Questions
How much fascia space is left for switches and indicator lights after fitting a controller?
With a single controller or thermostat mounted centrally, there's room either side for standard 22mm pilot lights or pushbuttons — handy for a simple "controller + run/fault lamp + isolator" layout on a boiler cupboard or plant room panel.
What if my controller or thermostat isn't one of the models listed above?
As a blank fascia with no window, it'll take most panel-mount PID controllers, digital thermostats and refrigeration controllers of similar size — just check your unit's cutout dimensions against the enclosure face before drilling.
Does it come with a viewing window?
No — this is the blank version, giving a clear fascia to cut and drill anywhere, unlike the windowed Indubox range (1303W, 1304R/W, 1306BR/W, 1308AR/W), which is built around fixed DIN-rail module positions instead.
Can I still fit DIN rail components inside as well?
Yes — DIN rail can be fitted internally (sold separately) alongside or instead of a flush-mounted controller.
