My house has an out building that I’ve converted into a home gym. I’m working on getting as much up off the floor as possible, so today I installed this wall mounted weight rack.
Installation was surprisingly easy, apart from driving massive lag bolts into 3.5mm pilot holes. I’m glad I didn’t listen to the directions that said to install the top 170cm (5’7") from the ground and instead did 183cm (6’), because the Olympic bar is just slightly off the ground.
The right most bolt didn’t quite line up with the stud, but it’s secure enough for now until I remove the top piece and throw in a large drywall toggle bolt.
Next up will be steel pegboards to hang things like resistance bands and handles from.
The toggle bolts I have are rated for 265lb a piece in 1/2in drywall, so a spanner board shouldn’t be necessary since it’ll have <50lb on it.
Bolts may be rated, but the drywall might have other ideas - but you’re thinking it through right with the relevant weight load you’re putting on it.
