What are the requirements needed to install this product?
- DOUBLE-HUNG WOOD WINDOWS
– Our product will not
work with vinyl casement or other windows.
- SASH MEASUREMENT
– Our product works only with 1 3/8” sash thickness. The thickness is the part
of the sash that rides in the channel only, not the entire thickness of where the butterfly lock (or other locking mechanism) sits.
Most industry-standard windows have a 1 3/8” thickness.

The parting bead is the separation of the channel between the upper and lower sash. The parting bead size is usually 1/2”, but can also be 3/8” depending on geographic location (i.e., New England area, California).
