<h3>About Tie Down Engineering</h3><p>Founded in 1969 and headquartered in Atlanta, Georgia, Tie Down Engineering has spent more than five decades earning its reputation as a global leader in custom manufacturing. What started as a focused effort to deliver better-engineered solutions for American industries has grown into a multi-division powerhouse serving markets that range from marine and mobile home to roofing, agriculture, renewable energy, and beyond. Every product Tie Down makes reflects an engineering-first philosophy — and, notably, they're all proudly made in the USA.</p><p>Tie Down operates six specialized manufacturing divisions, each dedicated to a specific market vertical. This structure lets the brand go deep rather than wide, developing purpose-built hardware that holds up under real-world conditions rather than generic components that merely check a box. Whether you're a boat owner, a contractor, or an OEM trailer manufacturer, there's a good chance Tie Down has already engineered the part you need.</p><h3>Trailer &amp; Marine Product Highlights</h3><p>Among the brand's most recognized product lines are its <a href="/6667-tie-down-eng-fender-1380">trailer fenders</a>, which are a staple for boat trailer owners and OEM builders alike. Tie Down offers fenders in galvanized steel, aluminum, and high-impact polyethylene, covering wheel sizes from 8 inches all the way up to 14–15 inches. Their innovative bracket-less plastic fender design mounts directly to the trailer frame without requiring separate fender brackets — a practical solution that simplifies installation and keeps the setup clean. UV-protected finishes on their plastic fenders resist fading, cracking, and degradation over time, making them a smart choice for trailers that see frequent saltwater exposure.</p><p>Equally important for safe trailering are Tie Down's <a href="/6667-tie-down-eng-safety-chains-cables-accessories-200888">safety chains, cables, and accessories</a>. These zinc-plated and galvanized products serve as the critical backup connection between a tow vehicle and its trailer, providing peace of mind in the unlikely event of coupler failure. Tie Down's safety chain lineup spans Class 2 through Class 4 ratings — from 3,500 lb. to well beyond 5,000 lb. carrying capacities — ensuring there's a properly rated option for light boat trailers and heavier-duty towing applications alike. Chains are sold in pairs and come with durable S-hooks for straightforward installation.</p><h3>Why Tie Down Engineering?</h3><ul style="list-style:disc"><li><strong>55+ years of manufacturing experience</strong> rooted in engineering excellence</li><li><strong>American-made products</strong> built with domestic craftsmanship</li><li><strong>Six specialized divisions</strong> serving marine, agricultural, roofing, and other industries</li><li><strong>Broad material selection</strong> — galvanized steel, aluminum, and high-impact polyethylene options</li><li><strong>OEM and aftermarket coverage</strong> for trailer builders and individual owners</li></ul><p>For anyone who trailers a boat, hauls equipment, or maintains a fleet of utility trailers, Tie Down Engineering's catalog represents a reliable, well-engineered choice backed by decades of field-proven performance.</p>

Product Details

The Tie Down Engineering 86916 Cross Beam 28" Extension is a purpose-built add-on component for the Dock Sides mounting system, designed to accommodate wider dock installations. This silver-finished extension attaches to the standard cross beam found in the Dock Sides Clamp Receiver with Cross Beam (part 86900) or the Slotted Receiver with Cross Beam (part 86901), effectively lengthening it to span docks that are six feet wide.

Key Features:

  • Extends the standard Dock Sides cross beam to fit 6-foot wide docks
  • Compatible with Dock Sides Clamp Receiver with Cross Beam and Slotted Receiver with Cross Beam
  • Pre-drilled for straightforward attachment to existing cross beam
  • Fasteners included for a complete, ready-to-install solution
  • Total extension length: 28 inches
  • Silver finish for a clean, corrosion-resistant appearance

Part of the modular Dock Sides component system, this extension integrates seamlessly into your existing setup without requiring any additional tools or hardware beyond what is included. Whether you have a wood-frame or compatible metal-frame dock, this extension makes it easy to expand the reach of your receiver assembly and unlock the full range of Dock Sides accessories for a wider dock platform.
