Hammer rig
Description Weight each Part No.
Hammer rig 196.35kg HM105
By mounting a hammer onto a rig, longer lengths of earth rods can be driven.
For projects where large quantities of rods are required cost savings can be achieved,
for example, by using single 8ft rods rather than 2 x 4ft rods which would need
couplers etc. Installation time is also considerably reduced.
Please specify length of rod to be driven and type of hammer to be used
when ordering.
