Screw-in inspection hatches for boat, canoe and kayak bulkheads. These keep the buoyancy tanks airtight and should be unscrewed to allow air circulation when the vessel is not in use. Failure to unscrew them can result in the tank exploding if left for a long time in a sunny position. Hatches also allow small items to be stored in dry conditions in the tank.
The hatches have rubber seals and come with stainless steel screws for installation.
These inspection hatches are available in black, white or clear plastic. The clear hatches have a transparent lid and an opaque white rim.
When the boat is not in use, the hatches should be unscrewed to allow air circulation but they must be firmly screwed into place while the boat is in use.
