CTI 54mm Closure Tool?

I know that AeroTech has closure casing tools, and just recently someone started working on closure tools for the 75 & 98mm CTI casings, but is there a need for a CTI 54mm closure tool, or is hand-tight sufficient?

The closure has two holes that look like a spanner wrench would fit, but I'm not sure what size/dimension spanner would fit.

Any thoughts?

Hand tight is sufficient...the seal is radial and not compression from the closures. Hand tight is good.

Good to know - thank you.

I have a 100% success rate with hand-tightening.

2 for two. It's making sense why CTI did not have a tool as a listed product. Still it's interesting that the closure has those two holes in it.

I think the tool would be more useful for getting the closure off if it got jammed or oxidized.

There is definitely potential for a tool being helpful in removal, especially after a suboptimal flight. I used to have a bicycling pin spanner tool that looked like it would do the job, but I never needed to try.

Now, 75mm is another story. There is a clever way to build, at least using gen2 hardware, without the tool, but it is best and more simple to use it.

I use double groove channellock (parrot-beak) pliers with the business end dipped in plastic-cote to prevent scratches. Works on all my metal and plastic retainers that get stubborn after a flight.

I still have one of those Park Tool bicycle spanners(green vinyl coated grip). It actually does fit those holes on the closure.
I too have never needed it, but keep it in the box anyway. Every time I go to remove the closure after cool down, it's already loose.

Cti has a tool for both 75 and 98mm already, had them for many years.

I never had a problem with an CTI 54er Casing but I use two of these to open casings that got stuck.
They are very nice since they do not hurt the casing.
