Hi, I've been sifting through the various options to properly secure conduit at the NEC mandated 3' intervals but I don't see any fasteners for conduit that has already been installed, and without offset bends. I have conduit running between boxes without any offsets. I'm wondering what options are available here... I guess it did things in the wrong order.

I know about one & two hole straps (they require offset bends) and I know about conduit clamps (they require a screw beneath the conduit). There must be something in between, i.e a conduit clamp that is fastened at the sides like a 2 hole strap?

Any advice appreciated!

EMT does not need to be secured every 3'. One strap every 10' and within 3' of each box.

I always made do with these since it's what all the supply houses had in stock. You have to spread eagle them to slide them under the conduit and then be a little adept at getting at the screw but they get the job done. As mentioned, you only need two on each 10' typical run.

There are several types of stand-off clamps available. The one pictured below is available at Home Depot. Plumbing dept.

Thanks all for your suggestions. I might take a closer look at Nickd83's suggested "Clamp Back Spacer".

surferdude2's suggested "Stand Off Pipe Strap" looks ideal but the legs look too long.... if only it was a bit shorter. But I could also modify this clamp's height with some metalwork.

The other issue I have is the clamps are being fastened with 1/4" masonry anchors. The material is plaster and brick, and it's not a strong hold a lot of the time.

EMT does not need to be secured every 3'. One strap every 10' and within 3' of each box.
Thanks for clarifying, I mixed that up.

How much space is there between the boxes?
It varies - there's one part that's less than 3' between boxes, but I believe a clamp is still technically required. I might skip that one.

Attached is a sketch of another design that could work, but all I could find are these and they're 4 bucks a pop, which seems outrageous for a 3/4" strap. But probably fine for just the exposed area where I think I only need 2 clamps with masonry anchors.
