Electronics-SalonD-SUB DB37 Male/Female Header Breakout Board, DSUB Terminal Block Connector.

So... besides me, eyeballing the DB number I needed since it was my first amazon purchase.It comes as shown, good material, didnt have any connection issues or short circuit using it. Since it doesn't come with holes for screws on corners or rail compatible casing you have to make a frame for it to encapsulate it and use it on a panel.It made me work on projects or use it on projects that used a DB37. Good purchase handles standard 24VDC which is what I use to work on panel for projects of Kawaski robot arms or PLC input/output signaling modules 24 VDC and up to 2A that I've work with at least. Havent use it with more amps since I handle power grid separate from signal grid and copper rail would need more width.
