Low Profile Secure Fit Spacer 1

Exactly what I needed to connect my Hedrick focuser to the AP threads on my CDK17 — the fit is rock solid and the .300" spacing gives me just enough backfocus for my imaging train. Doesn’t rattle or shift even with a heavy camera hanging off it.

The threading is precise and the .300" length is exactly what I needed to get the right back focus on my CDK20. Bolts onto the Hedrick focuser solidly with no wobble.

Had to swap out my old spacer because the threads just weren't grabbing right, but this one bolts on solidly with no wobble. The .300" length is perfect for achieving proper back focus on my setup.
