Truth 31639 Stud Bracket 11258 / 11257 Dyad Casement - 552002

Truth 11258 / 11257 Stud Bracket for Dyad Casement Operator

This is a replacement Stud Bracket used with the Truth Hardware Dyad Casement Window Operator. The bracket attaches to the window sash and engages the operator arm, allowing the window to open and close smoothly.

The same base bracket is used for both left-hand and right-hand applications. It becomes handed only once the stud is installed, so please choose the correct handing from the dropdown when ordering.

To determine handing, view the window from the interior. If the hinges are on the right and the window cranks open to the left, you need a right-hand bracket. If the hinges are on the left and the window opens to the right, you need a left-hand bracket.
