Aluminium enclosures

For over 30 years ROLEC have designed and manufactured innovative enclosures for outdoor and indoor industrial applications. Our extensive range features modern ergonomic design with high ingress protection, typically IP66 or IP67 as standard, with IP69K available to order on some models. Each ROLEC enclosure is designed for fast installation of your electronic and electrical components such as PCBs, cable glands, connectors, membrane keypads, chassis plates, terminal rails, switches etc. The enclosures are available in a huge range sizes and styles, and are manufactured in different materials to suit a wide range of applications. The programme includes aluminium, GRP polyester, stainless steel, ABS, polycarbonate and flame retardant and UV-stable ASA+PC enclosures.

All of our enclosures can be supplied fully customised and ready to use. Our factory is equipped to carry out all the modifications you may need. Talk to our sales team for more information.


aluCASE is a highly attractive and very versatile range of diecast aluminium enclosures for industrial electronics. The design is perfect for mounting to a wall or a machine, or for use as a mobile instrument. The enclosures are sealed to IP 67 for indoor and outdoor applications. Hot jet wash IP 69K is also available. The enclosures can be mounted without opening the lid which means your electronics remain protected at all times. Whatever the application, aluCASE provides the very best housing solution for your components.

Designer features include a recessed lid, for fitting a membrane keypad, front plate or product label, clip-on design covers in plastic or aluminium that hide the lid screws and mounting holes, integrated hinges and lid retaining straps (on most models). Two versions are available with transparent lids. Threaded screw bosses are provided in the base and lid for PCBs, mounting plates, DIN rails etc. An optional key lock provides security access. Cable glands and other accessories are also available.

We can supply aluCASE enclosures fully customised to your requirements.
