Duct Rods - Selection
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.
NOTE: These Duct Rodders are custom Built to order and are non-returnable except for warranty. Exercise caution when ordering.
