Abstract
A clamping apparatus is positioned adjacent the interior wall of a sealed compartment. The wall has an opening providing an entryway for a fiber optic cable to the interior of the compartment. The clamping apparatus applies compression forces to an annular cylindrical body of a flexibly resilient and deformable grommet supported in line with the opening to seal the opening. The grommet has a passageway for the cable. The clamping apparatus, which essentially surrounds and conforms to the annular body of the grommet, is operable to compress the grommet radially around the cable and to axially urge the end face against the wall of the opening. A clamp member having clamping surfaces for compressing two side by side grommets in line with two side by side cable openings in the wall is disclosed. A headed rod extending at an angle to the wall with the cable openings therein supports the clamp member for angled movement to effect the compressive radial and axial forces.
