Widely used: the double-opening hexagonal locking mechanism securely locks a variety of heating thermostats. The thermostat lock cover with key provides protection for radiator valves, smart radiator regulators installed in dining rooms, offices, living rooms and bedrooms, classrooms and industrial environments!
Universal thermostat protection box: this radiator thermostat protection box is suitable for most cylindrically shaped thermostats, fits heating thermostats with a diameter of 2.3 inches, length 4.5 inches or smaller, and the water valve below 1.18 inches is also suitable, we recommend you measure the size before purchasing.
Thermostat protection box with key: the thermostat protective cover with key prevents children and guests from tampering, damaging and unauthorised changing the thermostat settings, and also prevents pets such as dogs and cats from touching the thermostat. The outer corners of the protective box are polished and designed so that children and pets cannot be accidentally injured.
Friendly design: the waterproof, dustproof and heat-dissipating protective box of the heater controller has a hexagonal design that is robust and durable. It is not only UV-resistant, but also has anti-yellowing properties. And it comes with a protective plug that can be removed when you need to dissipate heat from the thermostat, and can be installed when you need to protect children and pets.
Easy installation: it can be installed without tools, which makes it easier to use. Just open the thermostat sealing box, put the sealing box over the thermostat, then install the dust plug in the small opening, padlock it and you're done.
