Here is a list of some of the items that I used to complete this project.  This is only a partial list.  It may be updated to include more items.

TV wall mount: Sanus SLF9 (excellent to the point of being perfect).  Vendor: COSTCO.

Smart TV:  LG 65UH615A.  This is a 65 inch diagonal flat screen smart TV.  It has 4 HDMI connectors, 1 optical audio, 1 Ethernet port, 1 USB port.  The image quality is very good.  This particular model was chosen mainly because the mounting screw holes are centered below half the vertical height.  This means that the TV can easily be mounted higher than your typical TV.  Most flat screen TV sets have their mounting screw holes centered.  We needed to have our TV clear the mantel and allow some space for the center surround speaker to shoot its audio just under the TV.  Vendor: COSTCO.

Mantel over the fireplace:  Stoll, Carolina Mantel, Aspire Rustic is a standard finish.  Size: 60” x 8” x 4”.  Cost $659.  Vendor: West Coast FirePlace, Santa Fe Springs, Calif.  Easy installation if you know where the studs are.  I had to use photographs of the fireplace rocks and the bare studs to confirm where the studs were located.  The texture coat wall made it difficult to get a stud finder reading some times.

Conduit pipe used to make HDMI and optical audio runs:  1 and 1/8 inch I.D. PVC thin wall.  I then used 1 and 1/2 inch thin wall cut into 1/2 inch segments to be used to glue and lock the conduit runs into the plastic (blue) boxes.  I had to use wire lubricant and a rubber mallet to get the pipe to run through my pre-drilled stud holes.

Rear wall speaker mounts: Panavise Stud Speaker Mount, Model 105108 (black).  Vendor: Orvac Electronics, Fullerton, Calif.  For the life of me, I could not remove the stock wall mount.  My intention was to remove the stud mount and attach the mount to a steel electrical box plate out of which ran the speaker wires.  I may call Panavise and get some advice as to how to unattach the wall mount portion of this mount.

Ceiling light wall (switch) dimmers:  Lutron, C L digital dimmer, model MACL-153MH-WH. (very good)  Vendor: Home Depot.  I love these dimmers.  You can preset the light level you want and simply turn the light switch on to that level.  You can easily override the preset to turn any of these dimmers on full.

TV bias light:  PPA Int’l OLS Home Accent Kit.  (does not provide a good white light).  I may replace this with a true white light source.

Fireplace Mortar:  I had to shoot caulking under the steel Stoll mantel to fill in the space between that metal shelf and the fireplace rocks.  Rutland, Fireplace Mortar, gray, 10.3 oz, interior use only.  It withstands 2,000 degrees F.  I paid $9.

HDMI cable from wall connector to TV:  Vanco, Ultra Slim HDMI High Speed Cable with Ethernet, SSHD03.  Vendor: Orvac Electronics, Fullerton, Calif.
