Scuttles can be made from the following materials:
• A36 mild (carbon) steel with these finishes:

Shop cleaned (SP3) and red-oxide primed. This is our standard finish.
Sandblasted to white metal (SP10) and primed with an inorganic zinc primer. Cathacoat 302 (also known as Devoe 302) is the primary inorganic zinc primer we use. This is a premium finish available at an additional cost.
Specialized paint / primer finishes are available at an additional cost. Custom paints may significantly increase the product price, since the paint systems cannot be re-used on other jobs.
Galvanizing is another premium finish available at an additional cost. This finish option also adds at least two weeks to the lead time.

• Grade 5000 series Aluminum

• 304 Stainless Steel

• 316 Stainless Steel

Scuttle cover features: (any material)
• 5/16” thick (for ABS Grade) or thicker if needed

• OPTIONAL: Scuttle cover can be insulated with a 2” thick layer of ceramic fiber or mineral wool, or fiberglass insulation behind a 10ga panel of sheet metal

• Ceramic fiber or mineral wool are great for insulating for heat

• Fiberglass insulation is great for insulating for heat or cold

Coaming dimensions:

• 3/8” thick = Steel, Aluminum, or Stainless Steel

• Minimum coaming height: 4”

• NOTE: a 1 inch diameter or larger drain must be installed in coaming by customer to prevent accumulation of water around hatch cover. Failure to install a drain can lead to corrosion of coaming, which may eventually cause hatch to leak. Coupling for drain can be installed by the manufacturer if customer indicates on a drawing the desired location for the drain.

Dog Arms and Mechanism:

• Stainless steel dog arms used on Aluminum scuttle covers

• Wheel-operated from below

• Operable with a hex wrench from topside, with direction arrows to indicate open position

• For scuttles made before February 2015, dog stud head had a slotted head instead of a hex head. T-wrenches are required for operating t-slot scuttles from topside.

Gaskets:

• 30 +/- 5 Durometer extruded neoprene, 3/4” x 1-1/4”•

• Computing gasket length

Spacing for Scuttle Cover Swing:

• To allow the scuttle cover to open to 90 degrees, the coaming must be a minimum of 12-1/2” away from the nearest bulkhead

ABS Type Approval / Classing Agency Approval:

• All scuttles are built to standards generally accepted by ABS, USCG, and other classing agencies. See link to ABS Explanation

• Scuttles do NOT carry ABS “Type” approval. For further explanation, click here.

• Drawings and release letters are available for submission for classing agency review.

• It is the responsibility of the customer to verify which certification requirements (i.e. ABS, USCG, DNV, SOLAS) apply to their vessel, and to check with their local governing agency as to the requirements for certifications for all of the items quoted, based on the use for each item on the vessel, and the location of each item as installed on the vessel. Depending on the requirements of the governing agency, additional testing at the manufacturing plant may be required. A separate fee will be charged for any testing.

• Scuttles conform to C-class fire rating - they are made of non-combustible materials, however, they are NOT designed or certified to resist the passage of fire from one space to another.
