The Truth Hardware (AmesburyTruth) 51.10 Encore is a non-handed, sill-mount awning window operator supplied with a silver spline. It sits in a cut-out in the sill, and its two arms ride in a 16" (406.4 mm) track fastened to the sash, keeping the mechanism largely concealed beneath the Tango handle and cover. Truth rates it for awning windows 20" to 60" (508 to 1524 mm) wide when paired with the correct awning hinges. The gear arms and drive worm are hardened steel with Truth's E-Gard coating for corrosion resistance. Often called an awning window crank, opener, winder, or operator.

Truth lists the matching track and slider assembly (11577.XX), Tango handle and cover pack (12614.XX), awning hinges, and PVC gasket (32658) under separate part numbers. If your existing operator is the rear-mount style that fastens with a back plate (21969.92) and machine screws, you need the Truth 51.12 rear-mount version rather than this sill-mount 51.10.
