I have now installed eight of these mounts on 55” and 65” inch TV’sI am at a loss to know what more I would want in a TV mountThe key features are:One-piece long wall plate is all assembled and can be placed on the wall without the TVIncludes a cardboard template that makes it easy to predetermine approximately were and what holes you will use to mount the one-piece long wall plateScrews to mount the One-piece long wall plate to studs are included.Two brackets with the necessary screws included attach to your TV and then once attached you can pick up the TV and hang the brackets onto One-piece long wall plate easily.Two tube clips with screws lock those brackets with TV onto wall plate.A lot of extra hardware so you have the right screws and spacers.Things to watch out for:The One-piece long wall plate as delivered is too tight for moving TV once assembled. It is better to loosen the six (6) pivot bolts before mounting the long wall plate on wall (not too much about a turn and a half each. For this you will need a Hex Key Wrench Set and an open end wrench set (strange but true I found two different size nuts). Check the feel of opening the plate before installation.To mount first install the two brackets on your TV then measure from bottom of TV to top of hook on bracket . With that measurement establishing the height of the One-piece long wall plate is easy. I have observed that many people want the TV too high in a living room this will strain the neck. I position the bottom of the TV 46 inches above the floor.A bedroom is different because for two reasons you are lying in bed and occasionally one must look over a too tall belly. I position the bottom of the TV 56 inches above the floor (check for overhead clearance before mounting.Find the wood studs you plan to mount wall plate to. Use the cardboard template to determine the position of the upper left lag screw and which two elongated holes work correctly for your studs. Drill a pilot hole for the first lag screw, then with a washer on the lag screw fasten the upper left side of the wall plate about one turn loose. Use a level to position the wall plate and drill the upper right hole and use a second lag screw with washer. Recheck level; recheck distance from floor to bottom of TV (as planned). Install lag screws three and four. Tighten all lag screws. Then Hang TV then connect TVIf for some reason the set is not level this can be adjusted at this point.Remember you may have exposed wires you don’t like. Please see my review of the Datacomm 50-3338-WH-KIT Easy Mount Cable Organizer Kit and PORTER-CABLE 43218 3/16-Inch Piloted Down Spiral Drywall Cutout Bit to help you with that problemGood LuckMounting to wood studs is easy.I have mounted some to metal studs using 1/4" X 3-1/4" T-Anchors - For Hollow Cavity Applications when you use this part you will need to add a lot of spacers or chase the threads further as the threads have not been chased far enough to tighten the screw. Also after you tighten screw you will probably want to cut off the excess thread.
