Oxbow rat food question

I have a hard time getting rat food and I was wondering if this is the lab block size. I can't tell from pics. I don't want it to fall the tub of my rat rack. I used 1/2" hardware cloth and unfortunately the dog food (emergency food) falls down and then they are eating where they crap. I really would rather keep the cage as clean as possible.

Is oxbow lab block the standard size I have seen before? I lost my source for lab block. It was no name though.

not sure what standard size is but looks right to me. but i like to stick with mazuri :)

Well I guess I mean big enough not to fit through the 1/2" mesh used on my rack.

All lab block I have see. Is larger so it isn't a problem. I just don't have choices here in northern ontario.
