Hella Marine 9NM 958 988-402 NaviLED Trio Windex Adaptor

Hella Marine 316 S/S NaviLED Trio Windex Adapter Nut (9NM 958 988-402)

The Hella Marine 9NM 958 988-402 is a specialized, precision-machined 316 Stainless Steel Adapter Nut designed to allow the seamless top-mounting of a Windex (or compatible) wind direction indicator directly onto the top cap of a Hella Marine NaviLED Trio tri-color navigation light. It solves masthead space constraints on sailing vessels by consolidating the navigation light and wind indicator onto a single mounting footprint at the top of the mast.

Precision-molded from corrosion-resistant marine-grade 316 stainless steel, this adapter nut replaces or fastens into the standard central securing shaft of the NaviLED Trio light housing. It features internal/external threads tailored to secure the light assembly while providing a threaded receiver post for standard Windex wind vane shaft fittings.

Key Features

• 316 Marine-Grade Stainless Steel Construction: Maximum resistance to pitting, crevice corrosion, and harsh salt spray at the masthead.

• Masthead Space Optimization: Integrates a wind vane directly above the tri-color light, reducing clutter on busy mast top plates.

• Precision Threaded Interface: Designed specifically to mate with the central locking shaft of the Hella Marine NaviLED Trio series and standard Windex shaft threads.

• Low-Profile & Lightweight Design: Minimizes weight-at-the-top-of-the-mast to avoid impacting vessel stability and sail performance.

• Corrosion-Proof Lock-Down: Prevents wind indicator displacement caused by wind vibration and rigging movement.
