I want to mount a PT 2 x 4 to a cinder block wall in my basement, in
order to build some shelves.

What is the best way to do this ? These shelves may hold a max of 100 lbs.

I have seen those lead "sleeves" which I suppose you screw lag bolts into.
Is that the best method ?

Are there other products which are easier to use ?

I do have some mortor bits, so I am guessing that I can drill into this
wall
ok. I don't think it is poured solid at this place in the wall.

Thanks for any tips.

No lead anchors and lags are not the best for hollow masonry, those
are good for solid slabs. For hollow cinder block I would not use any
anchor that expands in its hole. I would rather use a butterfly (or
mushroom style) molly bolt so as not to crack a block with a hole
expanding anchor. Better to have an anchor that expands on the other
side of the hole like a mushroom or butterfly molly. Quarter inch
bolts should be fine for 100lbs on 16-24 inch centers.


I agree with RickH. Toggle bolts would be best for hollow block. 1/4" or
larger should work fine. You just need to drill your holes in the hollow
areas. If it is real cinder block you can drill with a masonry bit and a
good drill. However if you have cement block you will need a hammer drill.
