A rotatable latch system is disclosed that provides controlled angular motion and mechanical retention in multiple planes. The system includes a base structure having a base neck, a base locking cap, and an angle limiting notch, and a latch defining a neck opening, a locking cap opening, and an angle limiting slot. The latch is rotatably coupled to the base structure such that the base neck and locking cap are received and retained within the latch openings, while the angle limiting slot and notch cooperate to define a limited range of rotation. The system resists both in-plane and out-of-plane disassembly forces and may include snap-fit joints, adjustable angular limits, or asymmetrical rotation ranges. The latch may include a strap slot or alternative coupling features, enabling integration with various mechanical, consumer, or industrial assemblies.
