HAZET

<h3>HAZET: Over 155 Years of German Tool-Making Excellence</h3><p>Few tool brands carry the weight of history that <strong>HAZET</strong> does. Founded in 1868 by Hermann Zerver in Remscheid, Germany, the company began as a small forge and has grown over more than 155 years into one of the most respected professional tool manufacturers in the world. The name itself is a nod to its origins — &quot;HA&quot; and &quot;ZET&quot; are the German pronunciations of the initials H and Z, drawn directly from the founder's name. Today, HAZET remains a fifth-generation family business, a distinction that speaks to the enduring values of craftsmanship and continuity that define the brand.</p><h3>Built for Professionals, Tested in Motorsport</h3><p>HAZET's reputation was forged alongside some of the most demanding environments in the world. The brand became an official supplier and technical partner to Porsche Motorsport, providing customized tools and tool trolleys built for the rigors of professional racing. That motorsport pedigree flows directly into every product HAZET makes — from precision torque wrenches to ergonomic <a href="/7896-hazet-screwdriver-16594">screwdrivers</a> — ensuring that tools designed for the racetrack are equally at home in any professional workshop.</p><p>HAZET manufactures specialty tools for many of the world's leading automotive brands, including Mercedes-Benz, BMW, Volkswagen, Audi, and Porsche. This close collaboration with car manufacturers has shaped HAZET's deep expertise in automotive tooling, making their instruments a staple in professional garages and dealerships across more than 100 countries.</p><h3>A Catalog Built on Precision and Range</h3><p>With a product portfolio spanning more than 6,000 items, HAZET covers virtually every hand tool need a professional could have. The lineup includes high-precision torque wrenches, ratchets, fine-tooth reversible mechanisms, pliers, pneumatic tools, and a full range of <a href="/7896-hazet-screwdriver-16594">screwdrivers</a> and <a href="/7896-hazet-screwdriver-bit-50499">screwdriver bits</a> — all engineered to exacting standards. For those who prefer a ready-to-go solution, <a href="/7896-hazet-screwdriver-set-47872">screwdriver sets</a> offer curated collections of the brand's best drivers in a single package, ideal for both workshop use and on-the-go service calls.</p><p>More than 75% of HAZET's products are manufactured in Germany across four modern production facilities, incorporating technologies ranging from traditional forging to CNC-controlled machining and collaborative robotics. This commitment to in-house German manufacturing underpins the brand's promise of consistent quality and long service life.</p><h3>Workshop Organization with the Legendary &quot;Assistent&quot;</h3><p>No discussion of HAZET would be complete without mentioning their iconic <a href="/7896-hazet-tool-cart-55375">tool carts</a>. The &quot;Assistent&quot; trolley series is one of the most recognized workshop storage systems in the professional trades, combining heavy-duty construction, smooth-rolling castors, locking drawers, and thoughtful organization into a product that has become synonymous with the HAZET name. Whether for a busy dealership service bay or a dedicated home workshop, HAZET tool carts bring the same level of German engineering precision to workspace organization as their hand tools do to every fastener.</p><h3>Quality, Reliability, and a Lifetime of Support</h3><p>HAZET backs most of its tools with a lifetime warranty against material defects and faulty workmanship — a testament to the confidence the brand places in its own manufacturing. Combined with decades of award recognition for engineering excellence, brand reliability, and customer satisfaction, HAZET stands as a benchmark for what professional-grade tools should be.</p>

Product Details

The CURT 51520 is a trailer brake controller adapter harness designed to bridge the gap between competitor vehicle-specific wiring harnesses and CURT trailer brake controllers. If you already have a Tekonsha, Reese, Draw-Tite, or Pro Series plug-in harness installed in your vehicle, this adapter eliminates the need to replace your existing wiring — simply connect this adapter and plug in your CURT brake controller.

Key Features:

  • Allows CURT brake controllers to be used with competitor plug-in harnesses
  • Compatible with Tekonsha, Reese, Draw-Tite, and Pro Series vehicle-specific harnesses
  • Connects to any CURT brake controller (except the Echo model)
  • Features two plugs — one mates to your existing competitor harness connector, the other connects to a CURT brake controller
  • Quick plug design for fast, tool-free installation
  • OEM-quality construction for reliable, road-safe performance

The CURT 51520 adapter harness is an ideal solution for anyone upgrading to a CURT brake controller without wanting to replace their existing vehicle wiring. Installation is straightforward and typically takes about one hour.
