The Truth Hardware (AmesburyTruth) 23.46 Dyad is a right-hand, rear-mounted operator for casement and single vent awning windows, in white. Its two-linked dyad design gives smooth, continuous crank control out to a 90° sash opening, and the detachable clip linkage lets the arm disengage from the sash for easy installation, cleaning, and service. The case, crank handle, and knob are high-pressure die-cast zinc with a hardened steel worm and gear, protected by Truth's electrostatically applied E-Gard coating for chip, scratch, and corrosion resistance. It pairs with Truth 14 Series concealed casement hinges and 34 Series 4-bar hinges. Often called a window crank, operator, or opener.
