Quoted from oyvindmo:
Having taken a closer look, I'm starting to wonder if cabinet mounted lighting is a no-go on Safecracker. At least on mine, there is really no_ clearance between the ramp assembly and the cabinet on the right side. While lifting, it's possible to wiggle right-to-left a bit, but the total clearance (left+right) is only about 1/8". Are the magnet strips thin enough that it will work?
Anyway, a suitable length would be 25-26".
The mounting magnetic strips are thin just under a 1/16" thick per each side, so it would be close. It's up to you, but I can make them shorter for your Safecracker without a problem.
As for where the bracket is located on the ramp, just don't attach the magnet strip to the cabinet in that location so it won't interfere with it.
Just let me know,
