Ashland 1491-120B Optima Short Dual-Arm Operator - W1491S

Ashland Optima Short Dual-Arm Casement Window Operator - Stainless Steel

The Ashland Optima Short Dual-Arm Operator is a heavy-duty casement window operator designed for both left- and right-hand applications. It is used together with the matching sash bracket and track assembly to open and close the window smoothly.

An integrated o-ring seal helps keep water out of the operator housing, and a composite assembly thermally insulates the operator to reduce heat and cold transfer into the home. The operator is rated to AAMA Commercial grade 901-96 cycle test, 101 load rating, and DP70.

This short-link version is intended for casement windows from 24" (609.6mm) up to 36" (914.4mm) in width. Handing is determined as viewed from the interior; please check the images to confirm left- or right-hand orientation before ordering.
