NorDav Vertical Swivel Plate Elevator Riser Block

$1,093.07 Including GST

The NorDav Vertical Swivel Plate Elevator Riser Block is a specialized, heavy-duty structural accessory engineered to overcome deck clearance bottlenecks. Precision-machined from a combination of high-density marine polymers and electro-polished duplex stainless steel, this robust riser block elevates your primary rotating swivel base. This vertical lift provides the vital extra clearance needed for watercraft hulls to clear high swim step borders or protruding transom rub-rails without sacrificing cargo weight ratings.

⚓ Component Allocation Notice: This listing is strictly for the standalone Vertical Swivel Plate Elevator Riser Block Assembly. While specific product imagery demonstrates how this riser block interlocks with primary **NorDav Swivel Davit frames and boat cradles**, the complete davit systems are shown for illustrative demo purposes only, are not included in this price and must be purchased separately.

  • 🔄 Universal Model Compatibility: Fully cross-compatible with all standard NorDav V-Series (Vertical) AND H-Series (Horizontal) Swivel Davit Systems.
  • 🔺 Critical Vertical Clearance: Generates immediate vertical height displacement to lift rotating cradle arms clear of high deck lips.
  • 🛡️ Heavy-Duty Marine Polymer Core: High-density compound absorbs punishing impact shocks and prevents metal-on-metal hull chafing.
  • 🔧 Zero-Tolerance Fitment: Pre-drilled to match factory hole dimensions for a completely rigid, wiggle-free through-bolt footprint.

Description

Premium High-Density Vertical Spacing Block for NorDav Rotating Swivel Cradle Bases

The NorDav Vertical Swivel Plate Elevator Riser Block provides an unyielding engineering solution for boat builders, luxury yacht owners and watercraft operators facing restricted transom lip heights. Standard swim steps frequently feature safety borders, raised moldings or thick perimeter rub-rails that can obstruct low-slung rotating davit frames. The elevator framework solves this architectural bottleneck completely, lifting the weight distribution path vertically. This ensures your heavy rigid inflatable boat (RIB) hull or jet ski cradle can pivot smoothly throughout full loading arcs, shifting load boundaries cleanly away from primary cockpit pathways.

Advanced Cross-Brand Versatility & Mechanical Synergy

Engineered for maximum utility across our entire watercraft handling architecture, this structural riser block functions flawlessly across all configurations. Whether your vessel utilizes the vertical-profile NorDav V-Series Lift to minimize upper deck footprints or the low-slung NorDav H-Series Swivel Bunks for deep platform integration, these elevator plates serve as a perfect mechanical anchor. The precision-milled block faces align perfectly under your existing quick-release base plates or permanent mounts, interlocking into a rock-solid, sway-free unit that dampens punishing engine vibration and rough-sea structural torque tracking.

Aerospace-Grade Structural Rigidity & Material Strategy

Constructed entirely from heavy-gauge, UV-stabilised industrial marine polymers and marine stainless steel, this high-leverage vertical riser block possesses immense mechanical load tolerance. It is built to absorb relentless vertical shearing forces, heavy impact waves and intense torque spikes when traversing rough open ocean swells. The smooth, rounded edges and close-tolerance fastener slots allow your main davit arm assembly to dock effortlessly, offering single-handed launch and retrieval sequences that remain entirely safe, fast and stress-free.

🔧 Official Swivel Plate Elevator Structural Installation Guide

Follow these verified shipwright steps to ensure a completely safe, rigid and waterproof riser block fitment:

  1. Clearance Marking Alignment: Place the swivel plate elevator block on your fiberglass or teak deck footprint. Position your quick-release plates or permanent davit mounts directly on top of the block to verify the tracking holes line up cleanly.
  2. Mark and Center-Punch: Use a fine marker or center-punch to transfer the mounting holes through the elevator block down onto the deck surface. Double-check under the platform to make sure your drill path clears all fuel lines, electrical wiring trunks and structural stringers.
  3. Drill and Core Relief: Drill your pilot holes matching your marine through-bolt specifications. (Pro-Tip for Cored Decks: If your swim platform uses a balsa or foam core, scrape away 10mm of core material inside the cavity and fill it with solid epoxy paste to isolate the inner core from moisture tracks).
  4. Marine-Grade Sealing: Generously apply a high-performance polyether or polyurethane marine adhesive sealant (such as 3M 5200 or Sikaflex 291) to the underside of the elevator block, between the block and the deck plate, and inside the drilled bolt cavities to create a completely hermetic, waterproof barrier.
  5. Backing Plate Counter-Anchoring: Pass your extended heavy-duty stainless steel fasteners down through the mount, the elevator block and the deck substrate. From the underside of the platform, always fit oversized structural marine backing plates and nylon-locking aircraft nuts to distribute the heavy vertical torque and payload forces evenly.
