Prometheus Flat Hop Tensioners (Flat Type) A replacement Hop Tensioner (AKA Nub) Designed to be used with the Prometheus Straight (flat) hop rubbers.
The pack includes two tensioners, a hard type and a soft type to use with different set ups
While these are designed to work in conjunction with Prometheus Straight hop rubbers we have had no problems using them with other brands of hop rubbers as long as the conventional rubbers mound is removed.
Please note that these might need modification to work with some inner barrels and/or hop units to account for different lengths in hop-windows.
