Electronics tray 4" series

I’m having a hard time figuring out what the tray with terminal blocks and hardware provide that the tray doesn’t. I’m sorry if i seem to be acting immature but i really need a detailed description illustrating the difference between the two.

@Faraznisar Can you please link to the two products you are asking about? I’m not sure what you are looking at.

Thanks for the concern and here it is https://bluerobotics.com/store/watertight-enclosures/4-series/wte4-etray-r1/

I still do not understand the original question. It is an electronics tray with hardware that allows you to mount the tray inside of a 4" enclosure.

I’m sorry, I understand now. The tray only includes the tray and hardware to mount it in the 4" enclosure. The tray + the terminal blocks includes the same plus terminal blocks for power distribution and euro terminals for connecting 6 ESCs to 6 thrusters. The terminal block option adds the things circled in red here:

That’s it. Thanks for helping me out.
