A baffle is a device used to dampen the effects of such things as friction, sound, light, or fluid. Specifically, a baffle is a surface which is placed inside an open area to inhibit direct motion from one part to another, without preventing motion altogether. A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation all other translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges like the elbow joint. Features. 316L Stainless Steel Hinged Baffle.
