This closure can protect 4 fusion splices (45mm length) of 2.4mm diameter after heat shrink. As a result of its small form factor, it is compatible with low bend G.657 fibre and can be installed in manhole of 30 x 30 cm. Two cables with diameter 3.8 to 6.2 mm can be connected inline or butt. This aerial and underground optical closure is available in black.
