As others have said, they're barely big enough to hold an ethernet cable. About half of them will break if you try to squeeze a cable into them (they're pretty fragile). These cable mounts are relatively invisible, however, and hold up fairly well (although peeling off the red protection to reveal the adhesive is a bear). As you can see from the picture, the tackiness of the brackets is good enough to run a fairly stiff ethernet cable around a chimney mantle and will even stick to fairly rough brick mortar. I would buy them again; The price is cheap enough for the victims, and the results are worth the effort.
