1.Material :

THE ROD

TID  rods are manufactured from state-of-the-art materials formulated to offer the high performance & durability demanded by our customers.

The core of the rod is manufactured by the pultrusion process. This involves impregnating high strength continuous glass fiber filaments with a liquefied resin. 
The fibers are drawn in to a heated die where the resin matrix is cured, bonding the fibers together and allowing mechanical loads to be transmitted through the matrix and distributed amongst the fibers.

THE FraMes
Frames are also a feature of the TID Tech systems. a larger footprint for stability; steel brake handles that will last forever; dual rod out-feeding positions and wheels inside the frame width. The two 
smallest sizes feature frames with the feedout built into the handle. All frames can be laid down on either side. These are just some of the design features that will make every unit more usable and friendly for the end user.

roD 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.

The chart below is a rough guide as to rod diameter selection, but the above factors should all be taken into consideration before making the final selection.

                                     SAFETY                                    

1. Never bend the fiberglass rod around a corner with a radius less than the Minimum Bend Radius 

specified in the Operating Specifications.

2. A large amount of energy is stored in the coiled fiberglass rod. Always maintain control over the 
free end of the rod when the brake is not applied.

3. Be prepared for the unexpected. Use recognized safety practices and wear recognized safety equipment.
