Smart Marine Round Inspection Hatch 8in White — 2-Pack Weather-tight Non-slip ABS

Smart Marine 8" round white inspection hatch is a weather-tight, non-slip ABS deck plate with a detachable cover designed for boats, yachts, trucks and RVs.

Built for marine environments, this inspection hatch combines solid ABS construction, an O-ring seal and a reinforced, non-slip surface to protect compartments while resisting UV and corrosion. It’s offered in 4", 6" and 8" inside diameters and is available as individual units or a 2-pack (select size and quantity at checkout). The hatch mounts with a deck flange and separate cover for simple access and secure closure.

How does this hatch stand up to saltwater and sun exposure?

The Smart Marine hatch uses UV-resistant, anti-corrosive ABS and an O-ring seal to keep water out and maintain strength under sunlight. The materials and design reduce fading, cracking and galvanic corrosion common in marine fittings.

• Solid ABS body resists UV degradation and weathering
• O-ring sealed cover for weather-tight protection
• Non-metallic parts reduce risk of galvanic corrosion

What sizes fit my boat, and how do the dimensions compare?

Choose from three inside-diameter sizes so you can match existing access openings or plan new installations. Each size lists both outside and inside dimensions to ensure a proper deck fit and clearance for your application.

• 4" inside — outside diameter 5.5" (141mm)
• 6" inside — outside diameter 7.7" (196mm)
• 8" inside — outside diameter 9.7" (245mm)

How easy is installation and what hardware is included?

Installation is straightforward: deck-mount the chassis, then attach the detachable cover. The hatch ships with stainless steel screws (check your deck material and sealant needs) and has pre-drilled, countersunk holes for a clean flush fit.

• Deck-mount design with separate cover and chassis
• Pre-drilled, countersunk holes for easier screw placement
• Stainless steel screws included; additional sealant recommended for watertight installation

What practical features improve daily use and access?

The hatch opens through a 180° rotation and features a smooth, reinforced face with a molded non-slip pattern. The detachable cover lets you reach compartments quickly while a reinforced rim keeps the hatch rigid under foot traffic.

• 180° opening for full access to compartments
• Molded non-slip surface for safe footing
• Reinforced construction for durability under load

Who is this for: The Smart Marine round inspection hatch is intended for boat owners, yacht crews, marine contractors, and owners of trucks or RVs who need a durable, weather-resistant access port.
