Frame Spacing: 8 Frame v. 10 Frame

[The15thMember]

I have used 8 frame mediums since I started beekeeping, but this year, as I have mentioned before, I got a 10 frame poly hive to try out.  I would have gotten it in 8 frame, but the company I decided on didn't offer it.  I have noticed that the spacing is much tighter in the 10 frame boxes.  I can easily get my index finger beside the end frames in my 8 frame boxes when the frames are pushed together, but I can barely get the end frames in and out of the 10 frame hive.  Is the frame spacing tighter in all 10 frame boxes?  Or is it just something with this poly hive?

 I don't know about the poly hive but different manufactures can use different spacing. Example I run 8 frame boxes, I always used the 13 3/4" boxes like Dadant sells, Mann Lakes and one other I know of are 14" wide. Frame spacing should remain the same with the frames up against each other and only the outside two different with respect to the side wall.

Yes, I always keep the frames tight together.

I have several different manufacturers of 8 frame boxes, and I've never noticed a significant difference like this between them.  I have boxes with slightly different wall thickness, but the inside dimensions are more or less identical.
