Thin 2" Adapter with brass locking ring and 3 large thumbscrews. Use when you need 11/32" more in-travel. (ADA20132)
Brand : Astro-Physics
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).
