This kit ONLY works with our EGLF3 large full-motion mount for TVs up to 78". Expands your EGLF3 to reach wood studs that are 24" apart. The EGLF3 can natively reach 16" studs. We've included a drilling template to make things really, really easy. So easy, in fact, one might say that even a primitive, paleolithic man could do it. All the hardware you'll need for installation's included, so you can skip that trip to the hardware store. (Though we've heard they've got a pretty fire candy selection... butterscotch discs? Heck, yeah.) Included decorative covers disguise raw mounting hardware and gives your mount the little bit of pizzazz it really deserves. Wait! Stop right there! Did we mention we're a little psychic, and know why you've come here today? Hmm... hmm... yes, it's becoming clear now. You've bought the Echogear full-motion mount for TVs up to 78". Yes, yes... the EGLF3. Yes, that's it. Oh! And you've realized you've got... hmm... 24" studs? Mmm-hmm. Thought so. Good, good. You've come to the right place. This extender kit, the EGLF3-EXT, is exactly what you need to get that beautiful TV up off its stand and up on the wall. (Told ya. Basically fortune tellers working over here at Echogear. Pretty amazing, right? Tell your friends.)
