First of all, are the cinder blocks hollow or filled. If filled, that’s better. If hollow, that is a little trickier. But for hollow block, I would use toggle bolts. The wings will spread the weight behind the block and support the flower boxes. On filled block, I would use lead wedge type anchors and rut them in with a concrete or stone adhesive. This will provide an adequate anchor to the block. Go to your local hardware store for the right anchors and toggle bolts, along with the adhesive.

I would hang the boxes using a cleat attached to the block using masonry nails or screws. The nails can be driven in with a hammer or power shot tool. Then attach the window boxes. The DIY network probably has a video to do this. Hope this helps.

I’m going to beg to differ

personally I would not drill into the block itself unless I had to. In the event I HAD to I would drill directly into the middle of the width of the block as this part is most often solid through to the other side of the block, by using a hammer drill. lead plugs put into the hole followed by screws.

I definitly wouldnt blow a hole/nail using a power shot gun on anything you might see some day.

I drill into the morter joints myself, easier to repair down the road, solid through to the other side and somewhat softer to drill into. I’ld insert a lead sleeve and then fasten a hook into that, then hang the planter on the hooks.

Good Luck

How is the siding attached to the cinder blocks? Are there wood furring strips? If so, you could possibly use these to hang the boxes from.

Charlie i believe there is wood furring strips…this is on a house i recently bought and the only reason i think there is furrin strips is on the back of the shop the top half of the siding got blown off in a storm and the are visible wood strips there.

I would secure them to the furring if there is some. If now, I would use lead nail in anchors http://www.confast.com/products/metal-hit-anchor.aspx

Toggle bolts will require too big a hole and you will have to hit the hollow part. There may be bond beams of solid concrete poured in the wall. The 1/4” nailins will require a small hole and block is relatively soft and easy to drill without a roto hammer. Use 1” long anchors as they will make a good anchor even if you hit a hollow spot. Longer ones will not grab if they don’t expand in concrete.

guys can i do this with my 18v Dewalt cordless or a milwaukee electric drill. Thats all i got. Also if i can find the furring…would i go through the furring and through the concrete behind it or just through the furring?

If you can access the furring strips, I would use screws just long enough to penetrate the strips but not the blocks.

Me too, what Charlie says ;-) It may take a few minutes to drill block with any rotary drill. Use a carbide tipped concrete rill if you end up having to drill the block. And, lengthen the anchors as described before to accommodate teh material you are hanging. You want 3/4 to 1 inch in the block.

I would use a flower box bracket and anchor it to the blocks with concrete anchors. You didnt mention how large the boxs are, but if they are typical window boxs, concrete anchors will hold the brackets fine.

In commercial applications when fastening to hollow core cmu blocks we use epoxy with tube screens. you drill the hole per the size of screen and insert the screen, and then fill with epoxy. then stuff in your fastener.

typically simpson set 22.

that might be a bit over kill for your purposes though.
