Ultimate Lock Rings, 4 Pack Red, White, Blue and Gold


One wouldn’t think you could improve on a simple thing like a lock ring, but we have. 

The new split clamp spline drive makes all other lock rings obsolete and clumsy to use. 

We started with custom extrusion of high strength aluminum with a splined exterior surface.

 We split the ring, and added a cross bolt that when even lightly tightened, applies a vice like grip on your dies. 

No tiny set screws that easily strip or damage your die threads. 

Then we added the famous Lee “O” ring because no matter how securely you have the lock ring clamped to the die, it will loosen in the press during operation without the friction of the “O” ring. 

The “O” ring allows you to finger tighten into your press and it will never loosen during operation yet you can easily remove your die with finger pressure.

Use with the handy slim profile lock ring wrench, works great when fitting dies on a turret or tool head. 

Dies are simply easier to install with the lock ring wrench.

  • Compatible with 7/8 x 14 threaded Lee reloading dies and Lee reloading presses.
  • Torque type splined exterior, for a no-slip grip.
  • "O" ring, anti-rotation, included. Never loosens during use.
