I am looking for an extendable pipe ( from 1 meter - 1.1 meter) Diameter approx 25mmIt will be sunk into the ground VERTICALLYWhen it is in use the extension will be above ground.When the grass is being cut the extension will be lowered to below ground.Can the extension be locked in place by a twisting action ( as on tripod legs)?Country:United Kingdom
