As long as the brick is solid, mine is up with just wall plugs and screws. Doesn’t seem to be going anywhere...although it’s not too far to fall.
When you fix into brickwork, the quality of the fix is variable based on where fixing lands. It's easy enough to miss the mortar beds by adjusting the height, but it could be in a perpend (vertical mortar joint), a solid bit of brick or hit a hollow bit within the brick itself. On a finger board, there are fixed positions for the screws. You may hit something good with one and the next one is rubbish. By using the plywood, you can put multiple fixings in the ply and hit to optimum spot on the bricks behind. Once this is solid, you can then fix the fingerboard to that at exactly the correct height and position you want. Best kind of fixings are something like these. You want 50-60mm in the wall, plus the thickness of ply :https://www.screwfix.com/p/easydrive-countersunk-concrete-screws-7-5-x-80mm-100-pack/8400h6mm holes in the wall. Will need an impact driver to put the screws in.
I hope there isn't a catnick lintel above the door. Hopefully it will be a concrete one

Not too far to fall, but can be serious anyway. My sister's friend had a friction fit pull-up bar that slipped out. She landed on her bum and busted her spine...
The doorway I want to hang it above is in a brick wall of a converted garage.
What, BitterEnd, you used a gym?
