Whitecap Industries

<h3>Whitecap Industries: The Builder's Trusted Choice in Marine Hardware</h3><p><strong>Whitecap Industries</strong> has been engineering and manufacturing premium marine hardware from its headquarters in Piscataway, New Jersey since 1986. Serving OEM boat builders, commercial yacht manufacturers, and aftermarket customers alike, Whitecap has built a decades-long reputation as one of the most reliable suppliers of custom-designed marine components in the industry.</p><h3>Engineering Meets the Open Water</h3><p>What sets Whitecap apart from generic hardware suppliers is the breadth and depth of its in-house manufacturing capabilities. The company's production competencies span casting, stamping, extrusion, rubber molding, injection molding, forging, plating, and teak woodworking — an unusually diverse toolkit that allows Whitecap to engineer solutions that most suppliers simply cannot match. Whether a builder needs a one-off custom cleat or a high-volume run of deck fittings, Whitecap's engineering and design staff work directly with customers to develop components that are both functional and aesthetically refined.</p><p>Every Whitecap product is backed by a <strong>100% lifetime guarantee</strong>, a testament to the confidence the company places in its own craftsmanship. With no minimum order requirements and a commitment to reliable delivery, it's easy to see why generations of builders have called Whitecap their go-to hardware partner.</p><h3>A Deep Catalog of Marine-Grade Products</h3><p>Whitecap's catalog covers virtually every hardware need a boat builder or owner might encounter. At the heart of the lineup is an extensive range of <strong>deck hardware</strong> — including cleats, hinges, latches, pad eyes, and rod holders — manufactured from marine-grade 304 and 316 stainless steel, chrome-plated brass, and engineered nylon. These materials are selected specifically for their ability to resist the corrosion, pitting, and UV degradation that saltwater environments demand.</p><p>The brand is equally well known for its <strong>teak wood products</strong>, which include swim platforms, cockpit tables, handrails, racks, holders, and director's chairs. Teak's natural oils make it an enduring choice for marine applications, and Whitecap's craftsmanship elevates standard teak components into genuine nautical accoutrements.</p><p>For anchoring and docking, Whitecap manufactures anchor chains, anchor rollers, mounts, and cleats — all built from heavy-duty stainless steel designed to hold fast season after season. The company also produces <strong>gas springs</strong> that deliver smooth, controlled operation for hatches, doors, and access panels aboard vessels of all sizes.</p><p>Rounding out the catalog are plumbing components, ventilation hardware, galley accessories, boarding handles, and fuel system fittings — making Whitecap a remarkably comprehensive single-source supplier for marine hardware needs.</p><h3>Custom Engineering &amp; Private Label</h3><p>One of Whitecap's most valued capabilities is its custom engineering and private-label program. The company designs and manufactures products to client specifications, and can also handle retail packaging design and fulfillment for partners who want finished, shelf-ready goods under their own brand. This OEM-focused model has made Whitecap an invisible but essential partner behind many well-known boat brands.</p><h3>Why Boaters &amp; Builders Choose Whitecap</h3><ul><li>Nearly four decades of marine hardware expertise since 1986</li><li>Lifetime guarantee on all products</li><li>Marine-grade materials including 304/316 stainless steel, teak, brass, and engineered polymers</li><li>Proprietary Duraplex stainless steel formulation for enhanced corrosion resistance</li><li>No minimum order requirements</li><li>Custom engineering, private-label, and OEM services available</li><li>Broad catalog spanning deck hardware, teak products, anchoring, plumbing, and more</li></ul>

Product Details

The Whitecap Industries 3904BP is a pair of black rubber grommets designed for marine applications. These grommets feature a 3-3/8 inch outer diameter and provide a professional finish while protecting wires, cables, and hoses passing through bulkheads, panels, or other mounting surfaces.

Key Features:

  • 3-3/8 inch outer diameter for secure fit in standard panel openings
  • Durable black rubber construction resists UV rays, saltwater, and weathering
  • Smooth edges prevent chafing and damage to wires and cables
  • Sold as a pair for convenient installation
  • Ideal for marine, RV, and automotive applications

These grommets are essential hardware for any boat or vehicle electrical installation, providing a clean appearance while protecting vulnerable wiring from sharp metal edges. The rubber material creates a watertight seal that helps prevent moisture intrusion at penetration points.
