Fiberglass Duct Rudders & Fish tapes,Duct Rodders/DuctRods/COBRA ConDUIT ROD
Fiberglass Duct Rodder
Duct Rodders are composed of fiber glass rod which was extrudedby fiber glass and high strength resin at high temperature. Thistype of rod has high tensile strength and flexibility. It wascovered by a high density polyethylene engineering plastic as itsprotect layer, which make duct rodder cover sliding on surface,durable, corrosion resistant and has good insulation performance,which make them safe for use in cable occupied duct.
High Density polyethylene (Grade: for the insulating andjacketing of Telecommunication Cables) is used in the outerdiameter coating.
Duct Rodders will equipped with different size reel according tothe length of rod. There are wheels on the reel, which make itconvenient for moving.
Light weight, durable, resistance to acid, alkali, agingresistant, corrosion resistant.
High tensile strength and bending properties, which make it togo through narrow pipes easily.
Good temperature adaptability, the product will not soften inhot weather / nor become brittle in cold weather. Its usabilitywill not be affected by temperature.
Outer protect layer are made of high density polyethyleneengineering plastic, which has good anti-UV capability.
Cover was coated with long-term UV-resistant polyethylene.
Its surface has the advantage of smooth, wear-resistant and longservice life.
There are meter marks on the protect layer of duct rodder, whichcan be used for measuring distance. Marks are printed byprofessional printing machine, which has the advantage of strongadhesion, clear writing, waterproof, anti-ultraviolet, it can bestill clear even after using many times.
There are several kinds of colors for the rod for yourchosen.
