  • DESCRIPTION: This unique face-mounted operator provides smooth, continuous control of casement and single vent awning windows. The dyad, or two-linked design, provides smooth operation of windows with both types of Truth Concealed Casement Hinges (Product lines #14 & #34). The detachable clip linkage allows this operator to be disengaged from the sash for easy assembly and installation. Three-point mounting feature provides increased stability of operator on the window. Also available with two-point mounting for special window designs. See drawing for further details.

    PRODUCT APPLICATION ASSISTANCE: If you are designing a new window profile, or are having difficulty selecting hardware for your window, please contact Truth. Our highly trained Product Specialists can assist you with the selection of the appropriate hardware to meet your performance requirements, as well as providing personalized application drawings.

    LOGO OPTIONS: Have you considered personalizing your window with your company name or logo? All of Truth’s operator handles are capable of accepting your own “signature”. Contact Truth for further details.

    WARRANTY: Protected under the terms of the Truth Warranty for Window and Door Manufacturers and Authorized Distributors. Refer to Truth’s Terms and Conditions for further details.

    CORROSION PROTECTION: Truth’s E-Gard® Hardware has a multi-stage coating process that produces a superior physical and aesthetic finish. Plus, it is resistant to a wider range of corrosive materials, including industrial cleaning materials and environmental pollutants. This proprietary process has been tested to be approximately three times better than common zinc plated finishes.

    For the severe conditions associated with coastal areas, Truth has stainless steel hardware. See Tech Note #7 for further information about corrosion protection and these special hardware options

    MATERIAL: High-pressure die-cast zinc case, crank handle and knob. Hardened steel worm and gear.

    FINISH: Electrostatically applied, durable coatings that provide excellent resistance to chipping, scratching and corrosion while maintaining color stability for years in direct sunlight. Please refer to Truth’s Color Chart for examples of Truth’s most popular finish options. Truth also offers a wide range of decorative “plated” finishes – contact Truth for additional information on availability of these finishes on specific product lines.

    ORDERING INFORMATION:

Optional mounting hardware (sold separately). #20947 – Backing Plates (2 per operator). #30591 – Detach clip (included with the operator – replacement pieces sold separately). #30812 – Rubber cork adhesive backed gasket (for 2-point mounting). #21306 – Protective red plastic spline cap (optional).

    RECOMMENDED SCREWS: Types of screws required determined by material of profile used. Refer to drawings for complete information on screw type and quantity needed (sold separately). For additional information regarding screw selection – see Truth Tips and Tech Note #11.

    TRUTH TIPS:

    • Before selecting an operator, the hinge should be selected depending upon desired window features and hinge requirements (example: egress vs. washability).
    • Operator and Stud Bracket handing is determined by the hinge side when viewed from the inside (commercially handed).
    • The Truth Dyad Operator should not be used with Egress style or Butt Hinges.
    • The Dyad Operator is not recommended for windows with stiff, slide by weatherstrip. To insure proper operation and long operator life, weatherstrip forces should be minimized. To find out if the weatherstrip forces are acceptable, the following procedure is suggested:
      • From a complete window package, disconnect the operator so that the sash opens and closes freely
      • Mount window plumb and square.
      • Connect spring scale or other force measuring device to lower lock side of the sash and measure the force required to completely close the window through its final one inch of travel.
      • Multiply the force from Step C by the sash width and divide by dimension “A” from Figure 1. For acceptable performance, this calculated force must be less than 150 lbs. If your window exceeds the forces as measured by the procedure outlined above, Truth recommends that the Dyad Operator not be used.
    • To insure the proper selection of window hardware and mounting locations that will provide the best operating results, please follow these simple steps:

      REFER TO FIGURE 1.

      1. Determine the space available for operator arm clearance in the closed position – see 1.438″ (33.3 mm) minimum dimension-center drawing.
      2. Choose a Stud Bracket that will best fit the profile and will maximize the “A” dimension.
      3. Choose an operator that is compatible with the bracket chosen in Step B.
      4. Once the operator is determined, check the elevation of the operator with respect to the hinge to insure the elevation of the operator does not fall below the stated minimums.
    • The “C” dimension taken from the tables shown, with each individual operator, should be used as the starting point for determining operator location relative to the bracket location. In most cases, this will be the correct location. If while closing the window, the operator arm comes in contact with the sash, then shift the operator away from the hinge side of the window. If the window will not come completely closed, and the operator has reached it’s fully closed position, then shift the operator towards the hinge side of the window.
    • Mounting Screws must pass through two PVC walls, or one PVC wall and one insert wall or one PVC wall and Truth Backing Plates (#20947). For this reason, it may be necessary to use a longer screw than is recommended.
    • For metal window profiles, Truth recommends machine screws. However, in most applications, sheet metal screws will provide adequate holding power.
    • A Spline Cap (#21306) is available to protect the operator splines from dirt and other windows from damage during shipping, installation, and final building construction.
    • Truth Stud Brackets shown in Figure 8 through Figure 12 will fit the majority of the profiles. In the event that the Stud Brackets shown will not satisfactorily fit a profile, other specialized Stud Brackets are available – see Brackets & Track Section.
    • Sash weight should be limited to 50 lbs. to insure ease of operation for the lifetime of the window. When used on a sash weighing over 50 lbs., operating effort will increase and operator life will be reduced.
    • When a Dyad Operator is installed in windows used in high rise applications over two stories, a Truth Limit Device, to restrict the amount of opening, may be necessary. Contact Truth for wind loading information.
    • For accurate hardware placement in vinyl or metal applications, predrilling is recommended.
    • Truth recommends that a Snubber be used at the center of the hinge side on any casement window which has a tendency to bow outwardly at the center in the closed position. Adding a Snubber may increase the negative air pressure rating of the window.
    • When selecting mounting screws for Truth hardware, coating compatibility is one of the most important criteria. For best corrosion resistance the coating on the screws should be the same as the coating on the hardware. For more information see Tech Note #11.

    INCLUDE TRUTH SPECS ON YOUR NEXT PROJECT Window operators shall be provided which allow easy adjustment of window position.

  • The easiest way to determine the handing of your casement window unit is from the INTERIOR (inside) of the home. If you have multiple windows, stand in front of each window in question and locate the locks. The lock location will determine the handing of the unit.

    All casement hardware, which includes locks, operators and hinges, are handed based on the lock location when viewed from the interior.

    Alternatively, handing can also be determined by the hinge side when viewed from the EXTERIOR.

    Examine the product image carefully when ordering. You should be able to see the difference between the left and right-hand side version.
