The ERGO-Core comes in handy during frequent use. This dispenser works much like a ball bearing and allows tape to be applied smoothly. The ERGO-Core dispenser is made out of two inter-connectable plastic parts for repeated use. It is simply inserted into the tape sleeve and is thus universally usable for tapes with a width up to 50 mm. European Patent registered (pending). The ERGO-Core has been optimized for use with the Defender EXA-TAPES®.
