Cal June Buoys

<h3>About Cal June &amp; Jim-Buoy</h3><p>Cal June, the North Hollywood, California-based company behind the iconic <strong>Jim-Buoy</strong> brand, has been a cornerstone of marine and pool safety for more than three decades. With a catalog spanning everything from life-saving ring buoys to robust mooring systems, Jim-Buoy has earned the trust of both recreational boaters and commercial maritime operators around the world.</p><p>What sets Cal June apart is an unwavering commitment to quality construction and safety certification. Many Jim-Buoy products meet or exceed U.S. Coast Guard (USCG) standards, and several carry SOLAS (Safety of Life at Sea) approval — making them a go-to choice not just for weekend boaters but also for commercial vessels, docks, and marine facilities that demand the highest level of reliability. Materials are chosen for longevity on the water: closed-cell foam cores resist compression and moisture, durable vinyl and polyethylene shells stand up to UV exposure and harsh weather, and hardware throughout is typically stainless steel or hot-dipped galvanized to resist corrosion.</p><p>The Jim-Buoy lineup is impressively broad. Horseshoe buoys and ring buoys come in a variety of sizes to meet different vessel requirements, while mooring buoys — including the well-regarded Mark V hard-shell series — feature virtually indestructible outer shells over high-density polyurethane foam cores. Channel marker buoys help navigators identify safe passages, and life floats are engineered to USCG-approved capacities for crews ranging from a handful of passengers to 22 or more. Even specialty items like winter stick buoys, designed in heavy-duty polyethylene to stay free in icy conditions, reflect the brand&apos;s thoughtful approach to real-world boating challenges.</p><p>Among the brand&apos;s most practical offerings are its <a href="/7281-cal-june-buoys-pickupmarkermast-buoys-202345">Pickup, Marker, and Mast Buoys</a> — versatile tools that let boaters mark anchors, hazards, fishing spots, dive locations, and race courses with confidence. Built from the same quality materials as the rest of the Jim-Buoy family, these buoys are straightforward, durable, and purpose-built for everyday use on the water.</p><p>Whether you&apos;re outfitting a personal watercraft, a commercial fishing vessel, a marina, or a community pool, Cal June&apos;s Jim-Buoy products deliver the dependability that safety-critical equipment demands. With a legacy built on consistent quality and a product range designed to cover virtually every buoyancy and marking need, it&apos;s easy to see why Jim-Buoy remains one of the most recognized names in marine safety.</p>

Product Details

The Cal June Buoys 4402T-W-21/2 is an 18-inch Premium Mark V mooring buoy engineered for demanding marine environments. Built with the toughest marine-grade plastics available, this professional-grade buoy features a rock-hard outer shell with a nominal 1/8-inch thickness and a high-density 2-pound polyurethane foam core for exceptional durability and buoyancy. The buoy includes a distinctive 2-inch blue identification band and accommodates a 2.5-inch internal diameter tube for mooring chain attachment.

Key Features:

  • Premium Mark V construction with ultra-durable marine-grade plastic shell
  • Nominal 1/8-inch thick outer shell for superior impact resistance
  • 2 lb. high-density polyurethane foam core for reliable flotation
  • 18-inch diameter for high visibility and stability
  • 2.5-inch internal tube diameter for secure chain attachment
  • 2-inch blue identification band around buoy
  • UV-resistant construction for long-term outdoor exposure

Installation Guidelines:

  • Use mooring chain 1/2-inch smaller in width than the tube internal diameter (2-inch chain recommended for this model)
  • Chain length should be approximately 1.5 times the water depth at high tide
  • Total chain weight must not exceed one-half of the buoy's buoyancy rating

Ideal for residential docks, marinas, and commercial mooring applications, this Cal June buoy provides reliable performance season after season. The Premium Mark V design ensures your watercraft remains securely moored while withstanding harsh saltwater, UV exposure, and impact from waves and debris.
