I am hoping the C&F Fly Box users out there can help me with a measurement or two.

I am considering trying some C&F Micro Slit inserts on the lid of one of my Richardson Box trays but before I start messing things up I need the dimensions of the inserts; not the boxes they fit in.

I THINK there are two different sizes; the regular size which fits in a box about 4" X 5" and a larger size which appears to fit in a box about 7" long.

The information I am after is:
  • What are the actual dimensions of the two different insert sizes?
  • Does the same size retaining clip fit both sizes of inserts?
I did look on the net but all I found was the dimensions of the fly boxes. I also contacted Sci Anglers but all they offered was to send me a catalog which I'm afraid won't have the insert measurements.

There isn't anyone close by who sells both sizes of the boxes and they are packaged in sealed cellophane which doesn't lend itself well to measuring without cutting open the package which won't please the fly shop if they WON'T work for me.

Any help anyone can offer will be appreciated!
