The Lee Ultimate Lock Rings (brand part no. 91640) from Lee Precision are a 4-pack of anodized aluminum lock rings in red, white, blue, and gold, each fitted with an O-ring for anti-rotation. Regarded as one of the best split-lock rings made, they use a torque-type splined exterior for a no-slip grip, so dies install and stay put with the help of a lock ring wrench. They fit any 7/8×14 threaded Lee reloading die or press, and the O-ring anti-rotation feature means they will not loosen during use.
