Our company produces Duct Rodders has 12 years of history, we generate different diameter of Duct Rodders, diameter range from 3mm to 15mm length of 15mm.Duct Rodders, 60m, 100m, 150m, 180m and a variety of specifications, of course also can according to the customer need to customize the length. The color of the rod is divided into white, yellow, orange, blue, black, green, red, we on the rod make m the number of markers, and can be used for the customers in the rod marker customers trademarks.

These are just some of the design features that will make every unit more usable and friendly for the end user.
Which is the right rod diameter for any given application? The rod selection is usually governed by several factors including:
The size of ducting it is to be pushed through
The distance the rod is to be pushed
The number and tightness of bends in the ducting
If the ducting is already occupied by cable
When being pushed through the duct, any rod will tend to form “sine waves”, hitting the wall of the duct at certain intervals.
Each time the rod comes in contact with the wall of the duct, it causes friction. The friction will build and eventually prevent the rod from being pushed any further. Small rod in large duct will make more frequent contact with the ducting; the same rod in smaller duct will make less frequent contact and therefore less friction so it can be pushed further. Large rod in small ducting is a good situation, but reduced flexibility of the rod may cause increased friction in the tighter bends.
