Hinge bender

According to the Norwegian Standard NS 3424, it is expected that a house door needs adjustment every 2 to 8 years.

If the tool instead is rotated away from the door, the opening between the hinge stile and casing will be increased.

Some common diameters for fixed-opening hinge benders in Europe are 14 and 17 mm (0.55 and 0.67 in).

[citation needed] In the United States, 0.134 and 0.180 gauge hinges are common, which have barrel diameters of 3⁄4 and 13⁄16 in (19 and 21 mm).

[citation needed] In Australia, some common hinge barrel diameters are 12 and 15 mm (0.47 and 0.59 in).
