3M STFF Joint Protection Sleeve

The LUL-approved 3M Smoke, Toxicity, Flame and Fume Protection Joint Sleeve (STFF) is made up of layers of woven glass fabric and high temperature silica to enable flame retardancy, and prevention of smoke and toxic fumes. The joint shield is designed for use with all single and three-core polymeric cold shrink joints up to 33kV, as well as LV cable abandonment applications.
