Does what it says
Tuesday, 15 October 2019  | 

Bought this to replace the 1.25" to 2" adapter on a stock Startravel 120 focuser.

I had already replaced the 45 degree prism diagonal with a 90 degree mirror diagonal and added a heavy Baader eyepiece in place of the stock 10mm / 25mm eyepieces that come with the scope.

The new train, and any subsequent train additions I might accumulate in the future we just a bit loose in the stock 1.25" to 2" adaptor, this new adaptor, although I've not had weather to put it to use, make the train a far firmer fit, and the grasping mechanism is less likely to damage or impinge on the diagonal.

At the time it was a toss up between completely changing the focuser for the Crayford type (which looks to have a better adaptor, or just get this for the time being).

I'm pretty happy for what it is, arrived quickly even by 1st Class Royal Mail.
