AT 29/360 end-closures?

Works fine. My DR 29/180-240 case "system" came with the "enlarged" aft closure, same as supplied with the 29/360. (I didn't even have a "standard" one until I later got a 29/60-100 set also).

They're interchangeable for the smaller motors; the "enlarged" version is required to assemble the 29/360 loads, since the aft part of the nozzle piece is larger in diameter.

(There's a similar situation with the 38mm motors - the longest ones (J570 etc.) need an "enlarged" closure; the shorter ones can be assembled with either the "enlarged" or "standard" part.)

At has a 5/8" nozzle stem and they also have a 3/4" IIRC. The closure IIRC does not fit snuglu on the 5/8" stem.

On a USR closure the part fits snugly on the 5/8" stem.

The way I understand it is that the 29/360 closures are unique to that case specifically. I can't find a place to buy just the 29/360 case without closures. They're all sold as a complete motor because a "special aft closure" is required.

My 29-180 / 240 system is fairly new. (mfg'd 05/2002) so it may have come with the enlarged aft closure. The I.D. of my rear closure measures .825" Does anyone know if the .825" rear closure is the same one supplied with the

Yes, that's the enlarged one.

The USR 360 system uses the same closures and nozzle blanks as all the other sizes down to 60. Universal parts matter to heavy users.
