Fiberglass Duct Rudders & Fish tapes

Fiberglass Duct Rodder

Duct Rodders are composed of fiber glass rod which was 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 use

in cable occupied duct.

High Density polyethylene (Grade: for the insulating and jacketing of Telecommunication Cables) is used

in the outer diameter coating.

Duct Rodders will equipped with different size reel according to the length of rod.

There are wheels on the

reel, which make it convenient for moving.

Light weight, durable, resistance to acid, alkali, aging resistant, corrosion resistant.

High tensile strength and bending properties, which make it to go through narrow pipes easily.

Good temperature adaptability, the product will not soften in hot weather / nor become brittle in cold

weather.

Its usability will not be affected by temperature.

Outer protect layer are made of high density polyethylene engineering 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 long service life.

There are meter marks on the protect layer of duct rodder, which can be used for measuring distance.

Marks are printed by professional printing machine, which has the advantage of strong adhesion, clear

writing, waterproof, anti-ultraviolet, it can be still clear even after using many times.

There are several kinds of colors for the rod for your chosen.
