CRL 12'' 4-Bar Hinge - Truth Hardware
The CRL 4-Bar Hinges are made out of zinc plated steel. These non-handed hinges are designed for use with casement and project-out windows. Hinges have a built in stop, which prevents the sash from opening greater than 55 degrees. Hinges are designed for casement windows that have a lip on the outside edge of the sash. The 4-Bar hinge mechanism allows the sash to project out from the frame before it pivots. The maximum recommended vent weight is 65 pounds (29.5 kg).
