The US Tactical Supply website doesn't always list dimensions, which was confusing me.

The Tactical Tailor Sniper Data Book Cover is 10" x 6.5", for the Sniper Data Book / Modular Sniper data book.

The 9200 / 9201 kits appear to be for the 4 5/8" x 7" loose-leaf "Rite in the Rain" products.

The 980-kit looks similar, except for the Tactical Field Book (hardbound).

Then there's the "Tactical Notebook Cover", for the 4"x6" Tactical Hip Pocket Notebook (spiral bound).

Rite in the Rain website has much better detail.
