Allen have incorporated an ingenious removable attachment pin to allow the user to replace the tii-on rope as it wears. Simply unscrew the upper insert, push down on the tii-on rope and remove the stainless steel crossbar. Install your replacement tii-on rope by pushing through the hole in the centre of the upper insert, slide the pin into place retaining the tii-on rope and screw the upper insert back into the deck. The lower insert is enclosed ensuring the design is watertight and the two parts have flats so they can be tightened and undone with simple tools.
The clever part of this system is that it is a one-hole insertion, so if you ever need to change the crossbar or block, you can do so without needing to drill more holes in the future.
