español al inglés Técnico/Ingeniería Electrónica / Ing. elect.

From a series of sentences on an Excel spreadsheet for a company that manufactures ducts, trunking, cable routing solutions (for offices it seems).

This from a section on "furniture boxes" (the term used on the company's website):

Características de la caja de mobiliario
La caja es ampliable ofreciendo respuesta a todas las necesidades.
Robustez en la fijación a mobiliario.
***La caja queda fijada a prueba de extracción de la clavija***.

Could this this mean that the box can be provisionally installed to test plug removal? Sorry there's no further context or pictures but it is what it is
