Casement, crank-out side hinge

Turn a handle and the whole sash swings open.

Casements hinge at the side and swing out at the angle you choose, catching breezes along the wall and opening from top to bottom. They suit spots that are awkward to reach, like over a kitchen sink, because one turn of the handle does the work.

Folding operator handle

The crank folds flat when you are not using it, so it stays clear of blinds, shades and the sill.

Multi-point locking

Locking hardware engages at several points along the sash, pulling it in for a tighter, safer seal.

Up to 1 1/8 inch glass

Choose 3/4-inch dual-pane or 1 1/8-inch triple-pane insulated glass in the Series 1665 frame.

Clear view or grids

Leave the tall pane clear for the view, or add flat, sculptured or simulated divided light grids.

Casement windows seal tightly, open fully for ventilation and catch side breezes, which are their biggest advantages. The drawbacks are that the sash swings outward, so it can conflict with walkways, patios or shrubs, and the crank hardware needs occasional care. They also usually cost more than sliders or hung windows of a similar size.
