Lithco L-Lastic Stretch Linen – steel rollers do not do an efficient job of transferring water to the rest of the dampening system. Traditionally a tightly knit linen material had been the covering of choice. With traditional linen no longer available, we offer this more efficient substitute – Lithco L-Lastic Stretch Linen. L-Lastic is also an excellent cover for the Intermediate Ductor Roller on all K-Series (KOR, KORA, KORS and KORD) Heidelberg presses. 25 yards/roll. See selection table for more size options.
