Baader's T-2 Spacer Ring Set gives you a way to adjust/set the rotational position of T-2 threaded components. Have a lock screw that faces in an inconvenient position? Slip one of the thin delrin spacer rings over the T-threads and the rotation angle is modified (changes the point at which the threads seat). Utilizing an individual ring in-between any T-threaded components also prevents the possibility of frozen threads due to temperature change or over-tightening.
The T-2 Spacer Ring Set comes with three each of 5 thicknesses of rings to give a range of adjustment (0.6/0.8/1.0/1.2/1.4mm).
The rings are supposed to be a somewhat tight fit and must be pressed down over male T threads with your fingers with a bit of pressure. Inside diameter = 41.3mm, outside diameter = 45.9mm.

Spacers work with useful thicknesses, but fit very tightPros: Cons: Comments:
The spacers are very useful, but the fit is too tight. I have to shave the inner face of the rings with an Xacto knife to get them to fit slightly snug over the T threads. If they are not shaved you may never get them off of the T adapter without damaging the threads

Great Set of Spacers: Split Them VersitilityPros: Cons: Comments:
These spaces allow you to tune in the back focus that optimizes your camera, filter and guider configuration. Nice variety of spacer options. Although each spacer is threaded, I prefer to split then (like a piston ring) to allow easier application and removal. My back focus is now spot on.

Work as expectedPros: Cons: Comments:
These rings are precisely moulded to match T2 threads. You will need to push them into the threads. To remove you will need to pry them out using precision slotted screw driver. They give are useful to get correct spacing for your adapters, rings and tubes.

Nice assortment for fine tuningPros: Cons: Comments:
This is a nice assortment for fine tuning back focus or lining up components on the light path. I believe the thinnest rings are about 0.6mm. It would be nice to have a few thinner rings as well, but the ones supplied cover a wide range. I most definitely recommend clipping the rings before trying to use them. This does not affect their function and makes them much easier to apply and remove.

Baader T2 Delrin Spacer Ring SetPros: Cons: Comments:
Lot's of complaints elsewhere on the rings almost impossible to seat on a T2 thread. It is possible but tough. These are delrin and hold there shape perfectly, so simply cut the ring and save yourself the effort.100% recommended.

Badder T2 ringsetPros: Cons: Comments:
I use the Rings for two things.
Ordination: I have a ST-80 with three 25mm T-2 spacers screwed into the focuser's draw tube and the guide camera screwed into the other end. The rings between the camera and the male threads of the extension tube allows a secure fit wile properly aligning the camera to the axis of the mount. I had to use three as spacers to allow this and prevent any flexure of the draw tube.
Equipment functionality: I have a .7" filter wheel which adapters and spacers interfere with the filters. The treads go to deep into the filter wheel. Placing these rings between the spacers allow the filter wheel to work, while giving a secure connection between the two parts.
A must for imaging.

Useless productPros: Cons:
Difficult To Focus,Poorly Machined,Difficult to UseComments:
The so-called "spacers" are not threaded and impossible to use. I've been trying for a long time to get an OAG to focus a guide camera and it cannot be done with spacers. Too long or too short. I thought this would be the solution but it was not there is no way to make them compatible with anything.

Helped me set the rotational position of my T-2 Quick ChangePros:
Difficult to UseComments:
I used these to allow me to set the rotational position of my T-2 Quick Changer on my Baader T2 prism diagonal. (I wanted the quick changer clamp to be positioned at the 6 o'clock position.) The spacer rings are not easy to get on. I ended up making a cut on one side of the ring with a scissor which then allowed me to slip it onto the diagonal's threads easily.

Accurate,Strong Construction,CompactCons: Comments:
Excellent product that is very usefull in getting spacing just right. Getting them over T threads was almost impossible even after I heated them so I ended up cutting them. Took one star off for that, otherwise great product.

Great for fine tuning spacingPros:
A Variety Of Sizes,Many Spacers IncludedCons:
Needs To Be Cut To Fit,Rings Need To Be Cut FitComments:
Great for tuning spacing for focal reducers, field flatteners and coma correctors. Even though the rings need to be cut to fit over my T threads, it really is not a problem and makes the ring easier to remove.

Did not fit over t-ring threadsPros: Cons: Comments:
Could not slip a one of them over the male T-ring threads to use a spacer on any of the several t-ring threaded accessories I own. The I.D. was cut too small on the batch I got.... useless 2 me.
