HARCO SINGLE PLANE SWIVEL 1IN

A single plane swivel allows rotation along one fixed axis only, rather than moving freely in multiple directions. That constraint is actually the point. In setups where you need controlled, predictable movement without the fitting wandering out of alignment, locking it to one plane keeps everything stable and repeatable. The Harco 75800 is built around that specific function, no ratcheting, no adjustable ends, just clean rotational movement in one plane at a 1-inch size.

This single plane swivel is manufactured by Harco Industries and is designed for applications requiring a secure and stable join, without adjustable ends or ratcheting mechanisms. It may be a suitable replacement if your current swivel shares these characteristics.
