The swell nut (expanding rubber sleeve does the swelling) levers are a simple way to secure the kayak hatches when under way.
They work in conjunction with the CNC oval hatch rings listed in the kayak section.
THREE are required for the bow hatch and Four are required for the aft hatch.
These items are priced individually.
An instruction booklet is included.
