The main idea is how the hanger attaches to the support and how it holds the pipe. An adjustable clevis is identified by a U-shaped yoke or clevis that supports a clamp around the pipe, combined with a threaded hanger rod and nuts to set the vertical position. This lets you fine-tune the height and alignment of the pipe run.

In the figure, the pipe rests in a small clevis-style cradle that is connected to a threaded rod with an adjusting nut, which is the hallmark of an adjustable clevis. This contrasts with other hangers: a riser clamp is a circular band around the pipe that bolts to the support and isn’t designed for height adjustment; a trapeze uses two parallel bars with a crosspiece to cradle the pipe from above, often for multiple pipes; a heavy strap is a wide metal strap wrapped around the pipe and secured to a support, without the clevis-style adjustment.
