ABSTRACT:
A rodent-proof aerial splice closure (20) includes a substantially hollow casing (30, 31) having substantial externally exposed plastic areas. The casing sections (30, 31) are moveable with respect to one another on a hinge (35) for accessing the interior of the casing. Clamps (50) provide for reversibly holding the casing sections (30, 31) closed. Cables can enter and exit the closure (20) through cable ports (45), which can be sealed by end-pieces (55). The exterior geometry of the closure (20) is such that substantially all exposed plastic surface regions which are accessible to rodent teeth are rounded with curvatures preferably greater than one inch radii, thus large enough to prevent rodent teeth from biting down thereon.
