¨Bandeja metálica paso Instalaciones 150 x 60

Instalación de bandeja ciega de chapa galvanizada de 150x60 mm, suspendida en el techo a distintas alturas. ¨

Hello, I was thinking about "Platte mit Blindwiderstand"
but I have to admit I have no idea about electricity; however, I didn´t find anything else that might be associated with "ciego"

Thanks a lot for your help!
