Caged/Trapped by iron bars... but how?

I'm trying to make a door that traps a player with the use of just 1 lever, but I can't have two blocks descending from a top or bottom sticky pistons without making it separate and therefore using 2 levers (unless there is a way...). It would also help if there was any way for one lever to activate the second lever at the same time, like, connecting them somehow. I also can't have redstone crawl up a wall. Right now I have them separated. Is there any way I can get what I want?

I'm on Bedrock if that is of any use.

If you want me to explain my goal clearer, I will reply to you with pleasure.

Thank you for your time. :)



(I adjusted it in the last image a little but overall same function, the best way I can achieve it.)

You could try using wind charges if you have those ._.

Not sure if it works in br, but in java one can update the center of three wall to cause an instant (and observer detectable) change down any length of wall…

"Leafstone" [​where an observer can detect changes in the distance to the nearest log] doesn't work in br IIRC.

If the wall is thick enough, you could use a piston (activated by a single bottom lever) that pushed a column of sand up to make the redstone conection powering the upper pistons.

Checked the leafstone bit, no, that won't work in BR.
If you could elaborate a little about the first and last part though? Apologies!

The only thing that I could gather is by replacing the iron bars with sand, causing the two rows of blocks to fall, but it isn't the look I'm going for.
Thank you :)

Did a bit of checking and the wall state update thing won't work in br either (per the wiki)
It uses the fact that (in java) a wall between two other walls will change blockstate if a block is placed atop it and this change permutes down instantly.
[I should have said 'height' rather than 'length' in the description as it works only to send a signal down (not up or sideways)]

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

The 3ʳᵈ option involves placing an additional [4ᵗʰ ] piston facing up at the bootom of the build.
The 4ᵗʰ piston is poweredalong with the bottom bar S-pistons (the three moving the iron bars up) with this fourth piston pushing a column of sand (or other gravity affected full block) up.
The top sand block then acts as a switch transfering redstone power from a source (always on) to the upper trio of bar S-pistons.
[At the top one would have Lever - Repeater - SAND_OR_AIR - {a line of redstone to power the upper pistons} where SAND_OR_AIR is the top of the sand column.]

Basically, it just uses gravity blocks instead of slime blocks to move up and down to switch the upper S-pistons between powered and unpowered; the advantage is that one can use any blocks for the walls nexts to the sand column instead of needing to use blocks with which slime doesn't interact.
