RNR Umbilical Sheath - 100' Entry 

Umbilical Sheath for confined space entry and rescue. This expandable sheath will quickly and easily bundle all lines (rope, air hose, and communication cable) into one sleek bundle, which is much less likely to snag. Installation is a snap. It expands in diameter by a factor of 1:3 so it will even swallow a bulky connector. Made of tough PET, in four neon bright colors. Abrasion resistant and designed to operate in temperatures of -103 F to 257 F. 3/4 in. size will accommodate up to 1 3/8 in. of material.
