Window in which the sash hardware is located near the midpoint of the stile to permit left/right sash rotation. | |

Window or door that moves along a horizontal groove. Some hardware variations also allow the pane to tilt in like a hopper window. |

Window or door that rolls along a horizontal track. When opened, the window is lifted away from the fixed pane and onto the track. Often used in patio doors. Some hardware variations also allow the pane to tilt in like a hopper window. |
