Product Description
Price is for each.
Manufacturer Part Number: 3430B
Black Nylon
Bolt Size: 3/16" x 5"
This hardware component is a compact, injection-molded fitting engineered for durability in marine environments. It features a rectangular base with a tapered profile for smooth insertion and movement within compatible tracks. The base measures approximately 5/8" x 2-3/8" (based on comparable models), though exact overall dimensions are not always specified in listings-focus is typically on functional compatibility rather than aesthetic measurements. At the top, it includes a threaded bolt protrusion (3/16" diameter x 5" length) with a rounded, metallic screw head for securing attachments. The entire piece is constructed from high-strength black nylon, which provides UV resistance, impact toughness, and lightweight properties while avoiding corrosion issues common with metal alternatives in saltwater exposure. The design incorporates a sliding channel on the underside that precisely fits 0.850-inch wide tracks, ensuring secure yet adjustable positioning without wobbling. This model is often sold individually or in pairs, and it may come with point-of-sale packaging for retail display. It includes a Proposition 65 warning for chemicals known to the State of California to cause health risks, which is standard for many nylon-based marine products.
Functions
This hinge serves multiple integrated functions in marine hardware systems:
Uses
This side mount slide deck hinge is predominantly used in boating and marine applications, particularly for customizable and adjustable overhead protection systems. Its intended environments include recreational boats, yachts, sailboats, and powerboats exposed to harsh outdoor conditions. Key uses include:

Functions
This hinge serves multiple integrated functions in marine hardware systems:
- Sliding Mechanism: The primary function is to enable linear adjustment along a pre-installed track on a boat's deck, gunwale, or side surface. The underside groove locks into the 0.850-inch track, allowing the hinge to glide smoothly for repositioning without tools, while friction or optional locks (sold separately) hold it in place during use.
- Hinging/Pivoting Action: It acts as a pivot point, permitting attached components to rotate or fold. The bolt at the top connects to frame elements (such as eye ends or tubing fittings), enabling angular movement up to approximately 180 degrees, depending on the setup, for collapsing or extending structures.
- Secure Attachment: The 3/16" x 5" bolt provides a robust threading point for fastening boat frame tubing or straps. It can accommodate standard marine fittings like jaw slides or eye ends, ensuring a tight, vibration-resistant connection that withstands wind, waves, and motion.
- Load Distribution: By mounting on the side or deck, it distributes weight and stress from overhead structures evenly across the track, reducing strain on mounting points and preventing damage to the boat's hull or surfaces.
- Environmental Resistance: The nylon material functions to resist fading, cracking, or degradation from sun, salt, and moisture, maintaining operational integrity over extended periods without requiring frequent maintenance. In operation, it combines sliding adjustability with hinged flexibility, making it ideal for dynamic setups where positioning needs to change based on conditions like sun angle or boat speed.
Uses
This side mount slide deck hinge is predominantly used in boating and marine applications, particularly for customizable and adjustable overhead protection systems. Its intended environments include recreational boats, yachts, sailboats, and powerboats exposed to harsh outdoor conditions. Key uses include:
- Bimini Top Installation and Adjustment: The most common application is securing and positioning bimini top frames. Mounted on side tracks along the boat's gunwales or cabin sides, it allows users to slide the hinge to adjust the canopy's coverage area, providing shade, rain protection, or UV blocking while boating. The sliding feature is especially useful for fine-tuning the top's span to fit different passenger configurations or to fold it away compactly when not in use.
- Dodger and Enclosure Mounting: It supports dodgers (forward-facing windshields or spray shields) and full canvas enclosures by providing a side-mounted pivot that can be adjusted along tracks for optimal fit around cockpits or helms. This is valuable on larger vessels where enclosures need to adapt to varying weather or navigation needs.
- Canvas and Sunshade Systems: Beyond bimini tops, it's employed for attaching adjustable sunshades, awnings, or temporary covers. The vertical side-mount orientation makes it suitable for attaching to cabin walls or raised deck edges, allowing frames to extend outward or fold inward.
- Other Adjustable Marine Hardware: In broader contexts, it can be used for mounting foldable tabletops, hatches, or accessory rails on decks, where sliding adjustment enhances usability (e.g., repositioning a table for dining or storage). It's also adaptable for custom rigging in sailboat setups, such as securing lines or lightweight gear that requires pivoting and positional flexibility.
- Replacement and Retrofit: Often purchased as a replacement part for worn-out hinges in existing boat top systems, it fits standard 0.850-inch tracks commonly found on many boat models. It's compatible with stainless steel or aluminum frames, and its nylon construction reduces weight compared to metal hinges, improving fuel efficiency on smaller vessels. This hinge is not intended for heavy-load structural applications (e.g., supporting masts or heavy equipment) but excels in lightweight, adjustable canvas systems. Installation typically involves sliding it into the track and bolting the frame, with no cutouts required-fasteners like #10 screws (not included) secure the track itself to the boat. Users appreciate its ease of use for quick adjustments without disassembling frames, making it a staple in DIY boat maintenance and upgrades. Variants in white nylon or with different track sizes (e.g., 1.050-inch) are available for color-matching or compatibility needs, as seen in related part numbers like 3403B (black, 0.850 track) or 3403W (white, 0.850 track).
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.
