Lightly used first version Orion 2" Low-Profile Dual-Speed Crayford Focuser in box with bolts and ingenious low-profile 2" to 1.25" adapter. Really the only obvious signs of use are the brightening of the area under the bolt heads in the bolt sockets, which you can see in the photos. Recommended for 8" and larger scopes, so about 10" tube diameter and larger. However it sits on two rails so it doesn't really matter unless the tube is very small.

According to the Agena Astro/Antares focuser webpage linked below, the height is 50.2mm with 1.25" adapter and 47.9 without. However they say "All measurements below are measured from the bottom end of the flat base plate. There will be an additional gap of 1-2mm between this base plate and the telescope tube which will depend on the diameter of your telescope tube" but I'm not clear on what that means.
No longer offered by Orion, they have a somewhat different design now with the same name. The current Antares version is like this one. Check the Antares listing for very detailed specs.
Also note this is heavy at 2lbs and you will want to seal the left and right edges with foam as they leave quite a gap that would allow dust into the OTA tube.

$115 shipped CONUS via USPS Priority Mail, PayPal preferred but not required.
