An hour, and you get the sideboard back. The stud finder is not optional.
This fits in a car
About 15 lb of materials. Comfortably inside what a car carries (200 lb), so any shopper can take it. ⚠️ 1 item on the list has no weight on file, so the real load is a little heavier than this.
Before you start
Studs only, never drywall anchors alone. And if you cannot find a stud where you want the TV, move the TV rather than trusting the anchor.
It lands in the shopping form, where you can edit anything and say what you think each thing costs. Nothing is ordered until you send it.
How it goes · about an hour · some experience
Find the studs and mark the centre of two of them. Every bolt goes into wood.
Hold the bracket up at the height you want, check it with the level, and mark the holes.
Drill pilot holes and drive the lag bolts in.
Bolt the arms to the back of the TV, then lift it on with somebody helping. It is heavier and more awkward than it looks.
