Marlow T12 is manufactured from Black Technora and offers a high stength, low stretch rope which has been a staple of the film and event rigging industry for many years. Flexible and easily spliced, extra abrasion resistance comes through the ArmourCoat coating. Care must be taken when specifying T12 in systems as it requires a large D:d ration of 20:1 plus in order to maintain optimum strength.
