The Leister PTFE dual pressure roller has two rollers: a 28 mm PTFE roll for overlaps and surfaces and an 8 mm PTFE roll on the back for detailed work in corners and narrow seams. The 8 mm PTFE roll does not overheat thanks to its heat-resistant material, preventing the membrane from burning through. The quick change between the two roles saves time and enables efficient work. The ergonomic wooden handle fits well in the hand and therefore ensures longer use.
