Duct rodder are composed of fiber glass rod which is extruded by fiber glass and
high strength resin at high temperature. This type of rod has high tensile
strength and flexibility. It was covered by a high density polyethylene
engineering plastic as its protect layer,which make duct rodder cover sliding on
surface,durable,corrosion resistant and has good insulation performance,which
make them safe for using in cable occupied duct. High Density polyethylene(grade:
for insulating and jacketing of Telecommunication cables) is used in the outer
diameter coating. Duct rodder will be equipped with different size reel according
to the length of rod. There are wheels on the reel,which make it convenient for
moving.
