Scuttles can be made from the following materials:
• A36 mild (carbon) steel with these finishes:
• 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
• 1/2” thick = Steel, Aluminum, or Stainless Steel
• Minimum coaming height: 6”
• Stainless steel dog arms used on Aluminum scuttle covers
• Distance from the top of the scuttle cover to top of hand wheel: 3-1/4”
• Distance from the top side of the scuttle cover to the bottom of the hand wheel: 9-5/16”
Spring Assist Hinge:
• 36” diameter is the maximum cover size in A36 steel that will work safely with a spring assist hinge
• 42” diameter is the maximum cover size in Aluminum that will work safely with a spring assist hinge
• 17-7 Stainless alloys are used for the spring wire. All hatches made after 2006 come with Stainless Steel springs. These alloys will experience some rust bloom, and will pull a magnet. The only steel alloy that will NOT rust or pull a magnet is 316 stainless.
• It is possible to put enough spring hinge assemblies with the proper tension to lift a larger hatch cover. However, once the cover is raised more than about 15 degrees, the springs will take over, ripping the hatch cover out of the hands of the person(s) opening the hatch, and will not stop until it hits the end of the safety chains. There is a potential to injure the people opening the hatch, and damage the spring-assist hinge mechanisms in the process.
• 30 +/- 5 Durometer extruded neoprene, 3/4” x 1-1/4”•
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.
