Heat Shrinkable Joint Closure  is a pressurized closure system based on a unique fiber reinforced heatshrinkable
composite material. This new revolutionary material offers extraordinary mechanical and environmental protection. Its
reinforced material structure has an excellent split resistance during installation and superior mechanical toughness. The closures have built-in visual indicators to ensure optimum installation under the most severe conditions.

The heat shrink closure is quick and easy to install using only a standard gas torch. The closure is completely wraparound allowing
it to be used for both new construction and maintenance on ducted or direct buried cables with polyethylene, lead and aluminium sheathing, up to 4 **0 pairs.Electronics three-fingered clips allow branching of up to
four cables at each end. The kit also contains a range of fully interchangeable air fittings
which can be incorporated in the closure. These include a reversible valve, an air
connector and a low profile blanking plug to reduce accidental damage.
