The Tempress Access Slam Hatches are constructed from a glass filled polypropylene, for strength and durability and are designed for heavy traffic areas. These hatches will withstand people walking or standing upon them. The Access Slam Hatch features an easy to close slam latch that forms a weather tight seal just by closing the hatch. Access Hatches also utilize a patented integral hinge assembly that allows for easy lid removal. The beveled and skirted lid covers all fasteners for a clean look above or below decks. The Tempress Access Slam Hatch line is the perfect choice for easy dry storage, access to bait or fish wells, or electrical and plumbing lines.
