Construction and properties
A Jumper Terminal consists of a main tube in aluminum coated with explosive and with a contact surface at one end. The contact surface is bent 15 degrees. Supplied complete with hot-dip galvanized bolts with accessories. The loop sleeve is not tensile. Several can be mounted at the same time.Loop sleeve consists of a main tube in aluminum coated with explosive and with a contact surface at one end. The contact surface is bent 15 degrees.

The explosion fixture can also be used for:
- Anchoring of steel cables.
- Bardun fasteners for antenna and high-voltage masts.

āāāāSpecial characteristics
The Jumper Terminal can be mounted with a 30 degree, possibly 0 degree extraction angle. Cold flow pressing of the aluminum tube eliminates welding joints and reduces the transition resistance in the contact surface.

Rules of use and safety
- Detonating fuse must be cut with a sharp knife or special tool suitable for this purpose.
- Detonating fuse must be initiated with a catch cap or teeth.
- Moist pentrite has low sensitivity; interruptions in detonation may occur.
- Dry pentrite has great sensitivity.
- If spills or remnants of detonating fuse are discovered after detonation, this must be collected and treated as an explosive item.
- Safety distance min. 50m upon detonation.
ā
Detonation
- Place the line ends with attached line joint in the shooting stand approx. 1m above the ground. A simple wooden stand can be used for this purpose.
- Make sure the connector is correctly mounted. Inaccuracy can cause reduced grip length and thus reduced holding power.
- Tape the catch cap to the explosive. Make sure that the trap cap is placed in the correct place as shown in the SPECIAL INSTRUCTIONS OF THE USER'S MANUAL, part 3, DETONATION, point 2, and that the trap cap lies in the longitudinal direction of the pipe close to the explosive.
- Carry out turnover of the charge.
- Remove any remnants of the PVC hose and the joint is finished.
