Inlet box and wall lamp connection box with Prefix® installation technology, for quick and easy installation against subsequently placed front formwork - without separate supporting element. Thanks to its spring-loaded wing brackets, this one-piece socket with two integrated front parts can be installed in such a way that its front surface will be pressed hard against the front formwork when it is subsequently placed, ensuring the socket will sit just right against the formwork and resulting in a smooth, clean finish after concreting.
