What is a Strap Hinge?

Strap hinges are among the most common choices for swinging door hardware. The distinguishing feature is a long panel – the “strap” – that attaches to the door itself, connected by a pintle to a shorter panel that attaches to the jamb. This basic design is remarkably flexible; strap hinges can be adjusted to work for almost any door, whether it’s a small residential one or a massive industrial installation that weighs thousands of pounds. Scaling up a strap hinge simply requires fabricators to cut longer and thicker straps, and possibly include a back plate to more evenly distribute the door’s weight.

Taking a Moment

A door’s “moment” is the force its hinges must bear each time it’s opened. While calculating a door’s moment may be trivial for small residential jobs, it is often critically important for large custom installations. The formula to find a door’s moment is very simple, and requires only two measurements – the door’s width and weight – to be multiplied together. The moment, combined with the door’s height, will determine what sort of hinges are appropriate, and how many will be needed. For example, if a door is four feet wide and weighs 1,000 pounds, its moment is 4,000 pounds; using this number, a manufacturer can then recommend the right hinges for the job depending on the door’s height.


Many people choose strap hinges for their doors not only for their strength, but also because of their classic look. Strap hinges can be cut into many different decorative designs while still maintaining their structural integrity, and buyers can choose from a wide variety of metals and finishes. Whether a buyer prefers a rustic colonial look or a sleek modern one, strap hinges can accomplish it. So long as the hinges can support the door’s moment, buyers are able to get very creative with their designs.
