2" Adapter with Brass Locking Ring (ADA2003A)

Brand :

In Stock

Custom CNC machined thumbscrews provide an elegant update to our 2" compression adapter. It features three custom machined 1/4-28 x 0.8" thumbscrews.

Use this adapter for critical applications and heavy loads, i.e. to center your CCD camera securely for an imaging run. 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 is also perfect with our ADASCTLM27 Adapter for large Meade SCT's and our ADASCTLC27 Adapter for large Celestron SCT's. This adapter attaches via 2.7" male threads.

This adapter has a net spacing distance of 0.77" (19.6 mm).
