This case just barely fits a fully assembled Stanley Bostich M111FN floor nailer with plenty of room for the hammer and some spare boxes of nails. The size in the description (56.1x37x26) is misleading because it suggests an interior width of ~14.6in (37cm) but it's actually closer to 17.3in (which is what you'd expect from the product specifications where the outside width is given as 19.29in). Glad I trusted the specs and pulled the trigger, finally having a case for this tool is SO worth the $90 and a much better value than certain other brands that specialize in hardshell cases that cost upwards of three times as much. Time will tell how it holds up but build quality looks good; the clasps lock solidly, there's four layers of pick&pull foam to work with so this would accommodate all kinds of uses, but for my purposes, as far as I can tell it's the only case on the market properly sized to fit the MF111N.
