Truth® Maxim 50.50 Dyad Operator, Split Arm, Sill Mount - Left Hand

The Truth® Maxim 50.50 Dyad operator is a replacement casement window operator designed for sill mount applications on a wide range of windows manufactured between 1999 and 2019. This split arm operator is frequently found in windows from brands like Caradco, Crestline, Hurd, Lincoln, Vetter, Weathershield, and others. Its compact, modern design allows for smooth opening and secure closing of casement sashes.

Constructed with a durable die cast body and a stamped steel arm, this operator is available with an E-Gard® corrosion resistant finish for standard environments or in coastal grade stainless steel for harsher conditions. The split arm design features an offset down linkage, paired with snap-on (not clip-on) linkage hardware, and is specific to left hand operation—verify your window's configuration before ordering.

This operator is suitable for casement windows with glass sizes of either 11" (27.9 cm) or 15" (38.1 cm). It is sold individually and does not include a crank handle or installation screws. Recommended screws are 6 pieces of #8 x 1" (25.4 mm) flat head sheet metal, which must be sourced separately. Color and finish options are selectable; verify compatibility with your window color and style before purchase.
