Helical rods: Aluminium-clad steel
Thimble: Malleable cast iron, hot dip galvanized
Fnenn represents a calculated breaking force.
The actual breaking force must be determined in a test with the rope used!
The thimbles and sub protection rods are not included in the delivery and must be ordered separately.
The nominal force of the thimbles must be observed.
The direction of lay of the sub protection rod is ""cross lay"" to the preformed dead end.
When ordering preformed dead ends for conductor wires with left-hand lay, a corresponding note is required.
The preformed dead end are supplied bent in a loop shape.
The individual helical rods are glued together to form a bundle. The contact surfaces are sanded.
There is a coloured marking on the rod bundles near the loop. It indicates the point
where the two legs of the helical rods should be placed on the sub protection rod at the start of assembly.
Attention! The direction of lay of the preformed dead ends must match the direction of lay of the outer layer of the rods/wires.
The preformed dead end consist of five or more helical rods glued together to form a bundle, which are coated with fine-grained sand on the inside to increase friction.
The loop of the helical conductor fitting is protected against abrasion by a thimble.
Deformation of the cable is avoided because the radial pressure is distributed over a large contact surface.

Additional information
The preformed dead end consist of three to five rods glued together to form a bundle, which are coated on the inside with a fine-grained metal oxide to increase friction. These dead ends are designed for the full tensioning of the separate support cable (left-hand outer layer). The advantage of dead ends compared with tensioning devices commonly used is that there is no bending of the relatively stiff supporting cable. It is recommended to protect the dead end loop from abrasion by means of a thimble. Deformation of the cable is avoided because the radial pressure is distributed over a large contact surface. These dead ends can be used to suspend self supporting figure-8-cables too. Two dead ends per suspension point are required for any such application.
Fnenn represents a calculated breaking force. The actual breaking force must be determined in a test with the rope used, on request.
Compared to the usual tensioning devices, these rod fittings offer the advantage that the relatively stiff catenary wire do not have to be bent.
Helical rods: Copper alloy (inside surfaces gritted)

Helical dead-ends (AB) can be used for full load tensioning of solid and stranded copper-conductors together with clevis thimbles (see B821). Please state if preformed dead ends for left-hand lay conductors are required. The preformed dead ends are furnished bent as loops with the rods glued together to a bundle. The inside surfaces are gritted. A coloured cross-over mark near the loop indicates the starting point of application.
Attention! They lay direction of both the preformed dead ends and the outer layer of the conductor must be the same.
Helical rods: Stainless steel (inside surfaces gritted)
Additional information
Fnenn represents a calculated breaking force. The actual breaking force must be determined in a test with the rope used! Only suitable for glass fibre rods
Helical dead-ends (AH) can be used for full load tensioning of stranded stainless steel conductors and glass fiber rods. Check the breaking load of clevis thimbles ( B821). Thimbles have to be ordered separately. Please state if dead-ends for left-hand lay conductors are required. The dead-ends are furnished bent as loops with the rods glued together to a bundle. The inside surfaces are gritted. A coloured cross-over mark near the loop indicates the starting point of application.
Attention! They lay direction of both the dead-ends and the outerlayer of the conductor must be the same.
