The benefit of a power kit where you can pull the elastic to increase the tension on a running fish is now a must have feature. There are various suitable versions but none like Interlastic. The twin holes allow one important option; you can locate a winder bung allowing you to store more of your valuable Hydrolastic in place. This will let you adjust the elastic when wear begins to show allowing you to get extended life from the lacy. Designed with a reinforced wall the handling position is ideal, leaving room for the bung to sit inside, just below the last hole.
