This is not compatible with a standard frame; it's not designed to be used without the side boards and foot boards. 

See photo. 

It has the white bracket which would have the wooden side rails hooked into it.  The Black frame is a standard frame that would allow you to screw into predrilled holes on a frame. For reference, the Black frame is centered on the headboard.  As you can see, even if the brackets matched they don't line up.  ( also don't get excited about the holes to the right of the bracket, they don't line up with s queen frame... if only they were a few inches over...) 

I can obviously drill my own holes, but then the white brackets shows because they are a few inches wider than the standard queen frame.

The frame itself.  It is sturdy and I like the white. Please note the markings on it are not the wood showing through, but a tan paint.
