NorDav 316 Stainless Steel Platform Extension Structural Support Brace
$944.28 Including GST
The NorDav 316 Stainless Steel Platform Extension Structural Support Brace is an indispensable, heavy-duty marine hardware component engineered for total system stabilization. Precision-crafted from marine-grade 316 stainless steel, this robust structural reinforcement bar bridges the load-bearing paths on cantilever setups, eliminating severe mechanical leverage forces and safeguarding your primary transom deck from structural stress tracking.
⚠️ CRITICAL COMPATIBILITY MANDATE: To ensure mechanical safety and operational stability, this Structural Support Brace MUST be used in conjunction with the high-capacity Platform Extensions PMND-60101 and PMND-60102. Without installing this dedicated support brace, the extended system tracking lacks adequate foundational stabilization and will be highly susceptible to structural flexing or mechanical failure under heavy watercraft transit loads.
⚓ Component Notice: This listing is strictly for the standalone Platform Extension Structural Support Brace. Primary swivel davit frames and extended plates are shown in product diagrams exclusively for illustrative demo purposes and are not included in this price.
- 🔄 Universal System Synergy: Fully cross-compatible across all NorDav V-Series (Vertical) AND H-Series (Horizontal) Swivel Davit frameworks.
- 🛡️ Elite Load Stabilization: Specifically designed to eliminate vertical deflection and flexing on heavy elevator extension tracks.
- 🌊 316 Stainless Steel Build: Constructed entirely from marine-grade anti-corrosive alloy to endure relentless open-ocean tracking and saltwater spray.
- 🔧 Rigid Interlock Footprint: Bolts directly to your structural plates to build an immovable, vibration-proof foundation mesh.

Description
Premium 316 Marine-Grade Stainless Steel Structural Reinforcement Stabilizer for V-Series & H-Series Extended Davits
The NorDav 316 Stainless Steel Platform Extension Structural Support Brace provides an unyielding load-distribution solution for boat builders, luxury yacht owners and watercraft operators deploying high-capacity cantilevered platforms. When lifting heavy rigid inflatable boats or high-yield jet ski watercraft hulls past the edge of the stern, massive downward leverage forces concentrate directly onto the rear mounting anchors. This premium marine-grade stabilizer bars bridge that structural gap entirely, securely transferring extreme shear stresses away from core transom fiberglass plates.
🚨 Absolute Engineering Stability Requirement
This hardware brace is a mandatory foundational asset that must be utilized alongside the NorDav Platform Extensions PMND-60101 and PMND-60102. Without integrating this dedicated structural reinforcement support brace, the extreme cantilever profiles of the large elevator plate tracks will not possess sufficient structural stabilization. Attempting to track heavy tender payloads on extended platforms without this stabilizing brace will lead to dangerous mechanical flexing, localized deck deformation and system instability during harsh blue-water transits.
Advanced Dual-Axis Compatibility & Anti-Vibration Design
Adhering to NorDav’s uncompromising standard of cross-brand versatility, this support bracket functions flawlessly across all heavy-lift transom environments. Whether your vessel utilizes the vertical-profile NorDav V-Series Lift to minimize swimming step clutter or the low-slung NorDav H-Series Swivel Bunks for flush platform integration, this reinforcement bar acts as the ultimate structural safeguard. It dampens punishing engine harmonic vibrations and severe structural torque spikes caused by rapid vessel pitching in rough following seas.

🔧 Official Structural Support Brace Fitment Guide
Follow these verified shipwright steps to ensure a completely safe, rigid and balanced stabilizer installation:
- Extension Plate Alignment: Ensure your primary high-capacity extension tracking plates (PMND-60101 or PMND-60102) are fully aligned and loosely coupled to the transom base anchors. Position the structural support brace underneath the extension body frame lines.
- Load Angle Mapping: Set the brace at its designated engineering angle to maximize load dispersion back against the reinforced core stringers of the hull transom wall. Mark out the pre-drilled fastening holes cleanly onto your platform substrate.
- Drilling and Core Isolation: Drill your pilot paths matching heavy-duty marine bolt dimensions. If working with cored fiberglass steps, scrape out 10mm of inner balsa/foam core inside the cavities and seal tightly with an marine epoxy compound to prevent moisture tracks.
- Hermetic Sealing & Through-Bolting: Apply a thick layer of marine-grade polyurethane adhesive sealant (such as Sikaflex 291 or 3M 5200) inside the hole paths. Drive your high-tensile stainless steel fasteners down, securing them from the underside with oversized marine backing plates and aircraft locknuts.
- Final Torque Sequence: Tighten all interlocking structural bolts evenly across the extensions and the support brace. Perform multiple mock loading cycles with your tender to verify the extension assembly remains completely rigid, solid and entirely free of deflection play.
