Manfrotto Umbrella Tilthead with Hotshoe with Shoe Lock

A great-value tilt adapter for using your on-camera flash on a stand. The tilt is ratcheted so it locks in place without having to over-tighten the screw.

This version has a locking screw on the hotshoe (not shown in the images) to firmly hold your flash in place and is compatible with the Nikon SB900.
