Oh ya,
Had the misfortune of dealing with some 4' strips from Lithonia, which had reluctant to K.O. type K.O.s [Linked Image]

After bashing the heck out of two ends, resorted to Unibit drilling (talk about a time consumer!).

The Machine which was pressing out those K.O.s must have been hung over that day (or week / month... etc. [Linked Image] )

Lithonia is not immune from reluctant K.O.s and resulting tweeked fixtures (or bleeding fingers, thrown fixtures, numerous curse words directed towards fixture and maker, etc...).
Had a whole bunch of Zumtobel Fluorescent Downlights which suffered from the same affliction - reluctant to K.O...K.O.s! [Linked Image]
These even had the "Pry-Out" slice in the K.O.s, for easier removal.

Man, those things sucked!
