Ashland® casement window operators and parts are designed to restore and maintain the smooth operation of your home's casement windows. These mechanisms, including split arm, dual arm, and dyad-style operators, work by controlling the pivoting movement of the window sash for reliable opening and closing. Whether you're replacing a worn-out operator, upgrading your handle, or searching for compatible covers, each component in our collection is engineered to meet original equipment standards for performance and fit.

Trusted Performance and Applications

Our selection of Ashland® operators is manufactured by AmesburyTruth, a leading name in window hardware. These parts fit a range of window brands, including Eagle, Marvin, and other major wood and vinyl window manufacturers. Operators are available in left-hand and right-hand versions for precise compatibility. Each operator is surface-mounted and includes durable arms and gear mechanisms to withstand frequent use and exposure to the elements.

Replacement and Installation Tips

Replacing a casement operator is straightforward: confirm the handing (left or right) by checking your existing operator or window marking. Use a screwdriver to remove the old operator, then align the new Ashland® operator with existing mounting holes for quick installation. For best results, pair your operator with a matching cover and handle, such as a left-hand operator cover or a folding handle for secure, ergonomic use. Always confirm arm length, base size, and spline diameter to ensure a perfect fit.

Frequently Asked Questions

  • How do I determine if I need a left-hand or right-hand operator?
    Check your existing operator or window label for markings ""L"" (left) or ""R"" (right), or observe which side the sash pivots from when viewed from inside.
  • Are Ashland® operators compatible with older window models?
    Yes, many operators fit legacy models from Eagle, Marvin, and other brands, provided dimensions and mounting style match.
  • Can I replace just the handle or cover?
    Absolutely. Handles and covers are sold separately and available for both left and right-hand operators, such as this right-hand operator cover.
  • Are installation instructions provided?
    Basic installation is tool-free; detailed instructions may be included with each part or found online via AmesburyTruth.
