This cable is not plenum rated which is what you want for in wall applications to meet electrical codes. You need to put "plenum" in the Monoprice search field and select an HDMI cable from those results that states it is plenum or CMP plenum rated. Being plenum rated really only relates to how the cable behaves when exposed to fire. It has nothing to do with the electrical quality of the cable.
Have always bought from Mono and never had a issue. recently upgraded some of m y HDMI cables for the Samsung Q7 i bought. Probably for the price will go and change all the cables because i like the ultra slim and covers the 4k 18 gbs. Thanks Mono, shipping was fast
