Product Description
Price is for each.
Manufacturer Part Number: 6221H
316 Stainless Steel
* Drilled for use with a quick release pin S-1020
The Whitecap Marine Products Concave Base Deck Hinge with 1/4"- (SKU: 6221H) is a specialized marine hardware component designed for mounting on curved or tubular surfaces, such as boat rails.
Item Description
This is a compact, heavy-duty deck hinge constructed from high-quality 316 stainless steel, offering excellent corrosion resistance suitable for harsh saltwater marine environments. It features a concave (curved) base that conforms closely to rounded tubing or rail surfaces (commonly 7/8" diameter rails), ensuring a secure and flush fit without gaps.
From the provided image, it appears as a polished stainless-steel fitting with a flat, rectangular concave base plate (curved underside), a raised vertical arm, and a horizontal threaded bolt/pin protruding from the top of the arm for connection.
Primary Uses
This hinge is primarily used in marine canvas and top systems, especially for:
The concave base makes it ideal for installation on curved boat rails (e.g., 7/8" stainless tubing), gunwales, or other rounded deck surfaces where a flat-base hinge wouldn't sit properly. It's commonly paired with eye-end fittings on tubing ends, allowing the structure to fold down or be detached when not in use.
Functionality
Overall, this is a reliable, low-profile fitting that enables easy deployment and stowage of protective or shading tops on recreational boats, yachts, and similar vessels, combining strength, corrosion resistance, and user-friendly quick-release features.

The Whitecap Marine Products Concave Base Deck Hinge with 1/4"- (SKU: 6221H) is a specialized marine hardware component designed for mounting on curved or tubular surfaces, such as boat rails.
Item Description
This is a compact, heavy-duty deck hinge constructed from high-quality 316 stainless steel, offering excellent corrosion resistance suitable for harsh saltwater marine environments. It features a concave (curved) base that conforms closely to rounded tubing or rail surfaces (commonly 7/8" diameter rails), ensuring a secure and flush fit without gaps.
- Base dimensions: 7/8" width X 2" length (with countersunk mounting holes for a clean installation).
- Bolt/pin size: 1/4"-20 threaded bolt (often a removable, spring-loaded pin for quick-release functionality in many similar models).
- Fasteners: Requires two #10 screws (not included) for mounting the base to the deck or rail.
- Design: The hinge forms a 90-degree angle, with a pivoting knuckle or eye that accepts a mating pin or bolt from the attached component (e.g., an eye end fitting on tubing). The pin is typically removable for easy disassembly.
From the provided image, it appears as a polished stainless-steel fitting with a flat, rectangular concave base plate (curved underside), a raised vertical arm, and a horizontal threaded bolt/pin protruding from the top of the arm for connection.
Primary Uses
This hinge is primarily used in marine canvas and top systems, especially for:
- Securing Bimini tops (foldable sunshades/canopies on boats).
- Attaching canvas enclosures, dodgers, or other removable boat coverings.
- Mounting rail-supported accessories that need to pivot or be quickly removed/stowed.
The concave base makes it ideal for installation on curved boat rails (e.g., 7/8" stainless tubing), gunwales, or other rounded deck surfaces where a flat-base hinge wouldn't sit properly. It's commonly paired with eye-end fittings on tubing ends, allowing the structure to fold down or be detached when not in use.
Functionality
- Pivoting motion: Provides a smooth 90-degree hinge point for folding or adjusting attached frames/tubing.
- Quick-release capability: The removable 1/4"-20 pin (often spring-loaded) allows fast attachment/removal of the bimini or canvas frame without tools-ideal for seasonal use, storage, or trailering.
- Secure mounting: The concave design distributes load evenly on curved rails, reducing stress and preventing slippage or wear.
- Durability: 316 stainless steel construction withstands UV exposure, saltwater, and constant movement/vibration on boats.
Overall, this is a reliable, low-profile fitting that enables easy deployment and stowage of protective or shading tops on recreational boats, yachts, and similar vessels, combining strength, corrosion resistance, and user-friendly quick-release features.
NOTE: The difference between packaged and not packaged items is that a packaged item has a card with either a plastic encasing (blister) or a polybag usually for displaying purposes.
