Notes:
1. 90 ⁰ Corners are designed for use with the shear block or screw spline system.

3. Do Not measure hole locations from locking corners.
4. All 4 1/2” vertical corners can be mated together or with any other corner regardless of system considerations.
5. The
90 ⁰ corner halves may be snapped together and used as a one piece vertical mullion.
6. Refer to current available extrusions for all possible combinations.
