Heat Shrink Shroud
Gala Heat Shrink Shrouds (GHSS) provides a watertight and
fume-tight seal where cables enters inside the Glands. The
Heat Shrinkable
Shrouds are internally coated with hot melt adhesive for
complete environmental protection from Moisture, Dust and
Water, according to IP 68 (Ingress Protection). These
shrouds are manufactured from high quality cross-linked
polyolefin material.
