Does this lock on the tstak ii, flat top (dwst17807)

Not directly. You need a ToughCase+ large box to lock on your TStak and then you can lock this box on the top.

Is it possible to purchase the 1/4 bit rails that fit into this box? I have a bunch of bits floating around that i would like to organize.

I used small rails from other DeWalt boxes and some plain rubbery ones. I stack about 3 of these on top of each other. They fit great! I also use some small rails to hold hex shank drill bits in this case. I'm also buying "Toolcool 10pcs 12 Holes Hex Shank Screwdriver Bit Holder Plastic Case" to cut down and add more bits.

where do I find the little inserts that go in there for holding bits?

If you need less than 20 of them - I did the math and you should buy the 4pk of the small cases at the blue big-box store when they’re on sale instead of 3D printing the bit holder inserts.

What are the dimensions of it ?

The depth inside is one inch, the outside thickness is 1-3/8".

Very Good and Strong

I bought two of these to organise all the loose drill bits from various sets I had lying around. The cases are sturdy, look great, and store away neatly.

Great boxes for small tools, parts, etc

Some reviewers complain about the size, at the current price point I can't find anything to complain about. These little boxes are fantastic. I work on computers. Computer work requires a bunch of small hard to store tools and parts. I break the tab off of all of them. These boxes are perfect, small, stackable and they'll lock together. I finally get to organize a three drawers full of stuff, no more digging around to find what I need. Ordered more!
