Right Hand 9-1/2" Truth Straight Arm Casement Window Operator

Truth® Straight Arm Casement Operator, 9-1/2" Right Hand

The Truth® Straight Arm Casement Operator is designed for use primarily with wood casement windows that require a right-hand operator. This operator features a straight, non-offset arm for smooth and reliable window opening and closing. The arm measures 9-1/2" (241.3mm) from the center of the operator to the center of the button, making it compatible with a wide range of wood window brands that use this standard configuration.

The operator utilizes a nylon roller for smooth movement and stability, with a roller size of 9/16" (14.3mm) in diameter and 3/16" (4.8mm) thick. The base has eight holes for mounting, referenced as "8 Hole Base 45251," and the arm is marked with "40049 / 40050." The handle spline measures 11/32" (8.7mm) in diameter, which is important when selecting a compatible crank handle. Right-hand cranks use a gold spline, while left-hand versions use a silver spline for easy identification. For left-hand installations, refer to part number 55031, which may have limited inventory.

Available in several color options, including Bronze, Gold, and Chestnut Bronze. Note that the gold color has changed slightly since the mid-1990s. If your original hardware was lacquered or is older, the new gold finish could appear noticeably different, particularly if the finish was altered by paint or lacquer over time.
