Description

Designed for stable mounting and easy servicing, this stainless‑steel flag hinge pairs a window‑frame base on the jamb side with a wing‑shaped leaf on the door side. The lift‑off removable pin lets you raise the door off the hinge without undoing screws, while the 2BB bearing stack delivers a smooth, quiet swing. Made from SS304/201 and finished to match interior hardware packages, it installs predictably using a template screw pattern and suits residential and light‑commercial wooden doors.
