Description

Use this adapter for critical applications and heavy loads where more in-travel is required. This adapter is 11/32" thinner than our regular 2" Adapter. It threads into our 2.7", 3.5" and 4" focusers. If you prefer to use just one thumbscrew on occasion (perhaps if you are interchanging accessories frequently), simply remove the extra 2 thumbscrews for that session.

This adapter attaches via 2.7" male threads.

This adapter has a net spacing distance of 0.43" (10.9 mm).

This little adapter gave me just enough extra room to reach focus with my heavy eyepiece setup. The three thumbscrews feel solid and grip the barrel securely.

Finally got the extra in-travel I needed for a heavy lens setup, and the 11/32" thinner profile made all the difference. The three thumbscrews lock everything down solid without needing a tool.

Was a bit nervous about adding another piece to my rig, but this adapter is a champ. The 11/32" thinner profile gave me just the extra in-travel I needed for a heavy setup, and those three thumbscrews lock things down solidly without any tools.
