Abranet medium density Unipad 150 mm (6″) for all hole combinations. This Abranet unipad is optimized for flat surfaces and has a high edge durability. 15 larger holes allow use of conventional discs with 6 h, 6 + 1 h, 9 h and 15 h. Suitable for narrow shroud machines but not recommended to be used with 150 mm ROS machines, because the combination of Unipad + wide/Abranet shroud machines does not give the optimal dust extraction. Delivered with one 150 mm (6″) pad saver. To ensure correct installation, always use the supplied spacing washers, making sure that a minimum gap exists between the sander’s shroud and the top part of the backing pad, to prevent friction between the two parts. Tighten the screw hard. The backing pad should never turn idle. From time to time, check that the screw is well tight.
