NorDav V-Series Extended Spring-Loaded Rotation Lock Pin

Description

Premium 316 Stainless Steel Extended Indexing Plunger Lock for V-Series Swivel Davits

The NorDav V-Series Extended Spring-Loaded Rotation Lock Pin provides an unyielding mechanical safeguard for boat builders, luxury yacht owners and watercraft operators utilizing deep transom extensions. Standard length locking pins cannot reach the indexing channels when davit frames are set back onto structural extension tracking plates. This heavy-duty, extended-reach 316 stainless steel indexing assembly solves this issue perfectly, acting as an absolute physical lock to anchor your boat cradle into a rock-solid transit configuration.

Advanced Marine Metallurgy & High-Tensile Extended Action

Constructed entirely from industrial-grade 316 marine-grade stainless steel, this high-yield extended rotation stop is engineered to absorb intense lateral torque forces and continuous structural vibration. The internal spring mechanism maintains uniform compression even when subjected to intense salt crusting and baking UV exposure, ensuring a reliable lock every time. The extended plunger profile is precision-milled to drop into deep swivel tracking channels seamlessly, minimizing friction and avoiding surface binding.

Flawless Tool-Free Operation on the Transom Deck

Adhering to NorDav’s uncompromising standard of user convenience, the spring-loaded quick-disconnect workflow is completely straightforward. To unlock your davit platform for launch or recovery sequences, simply pull back on the heavy-duty stainless steel ring collar to disengage the extended plunger tracking. Once the tender is retrieved and rotated back into its optimal traveling alignment, release the ring and the heavy plunger automatically springs forward, locking the entire unit securely back into a single, sway-free footprint.

🔧 Official Extended Rotation Lock Pin Fitment & Maintenance Guide

Follow these verified technical steps to ensure optimal, binding-free mechanical indexing operation:

1. Extension Plate Track Verification: Ensure your primary NorDav V-Series swivel plate and custom extension tracking plates are clean and free of heavy salt debris. Rotate the davit arm back into its square traveling position to align the mounting collar hole path perfectly with the extended frame’s receiver track.
2. Thread Engagement Torque: Thread the extended 316 stainless steel lock casing down into the pre-drilled mechanical receiver hole on your extended davit structure. Tighten firmly using standard hand tools, ensuring the hex collar sits completely flush against the frame surface with no cross-threading tracking.
3. Extended Plunger Clearance Test: Pull the spring-loaded release ring manually to verify the pin draws back fully inside the sleeve casing. Release the ring; the extended plunger must spring forward smoothly and extend down completely into the deep swivel plate indexing slot with zero mechanical binding.
4. Anti-Seize Maritime Protection: Always apply a light layer of high-grade marine Teflon grease or anti-seize compound directly to the internal tracking thread and the tip of the extended plunger pin during seasonal maintenance intervals. This simple step keeps the spring action smooth and completely blocks salt crystallization inside the casing.
