Optima™ Dual-Arm Casement Operator
Dual-arm casement operator for sashes 24" to 36" wide, running on the W1491-75A track assembly. Unique O-ring seal holds back 4x more water, and longer nesting cranks give up to 15% more mechanical advantage. PDF brochure available.
The Optima™ dual-arm operator carries casement sashes from 24" [609 mm] to 36" [914 mm] wide, working with the W1491-75A stainless track assembly and a sash bracket.
Longer visual nesting cranks give up to 15% greater mechanical advantage than the previous generation, and the low wear joint connections keep operating effort low over the life of the window. Tested to DP70 in both impact and non-impact markets.
