Strap hinges are hinges designed for heavy duty applications and are usually associated with doors or gates. They have two components--a post plate and a gate plate (door plate). The post plate is usually rectangular while the gate plate is triangular or strap-like. Strap hinges are decorative and often come with a decorative shape at the tip of their gate plate. When installing a strap hinge it is important to select the right hinge for your project. So, before you begin installation you need to know the size and weight of the door or the gate that you will be adding the strap hinges to.
Tip #1 – Select the Right Size Strap Hinge
Strap hinges come in a variety of sizes. The smaller hinges are best suited for light weigh gates or decorative accents. The largest strap hinges will be best suited for exterior door and heavy gate applications. You can find the load limits for each strap hinge on its packaging or in the installation manual.
Tip #2 – Consider Weight Capacity
Each strap hinge has a maximum weight load capacity and you can obtain this information from the packaging. If you exceed this weight load capacity, your gate or door may break free from its jam or post. If you are installing a heavy gate or door you can utilize multiple strap hinges to compensate for the extra weight. If you use more than 1 strap hinge in the installation of your door or gate, make sure you space them evenly.
Tip #3 – Select the Right Hing for the Right Use
Strap hinges come in several varieties. Some are designed to be a gate hinge and others are designed to be used as door hinges. Some, such as the dummy strap hinge, are merely decorative. If you use the wrong type of strap hinge for your project, the hinge may fail or your hinges may look out of proportion for your gate or door.
Tip #4 – Know Which Way the Door/Gate Should Swing
Door hinges are generally going to swing in one direction while gate hinges will offer you a fixed swinging direction or a bi-directional swing. If you want your gate to be able to swing both forward and backward, then you will want to find a strap hinge that has a pintle connection. This option will not only allow your gate to swing both directions, but it will allow you to lift your gate off its post hinge once the pintle hinge has been connected to the gate and post. This is a great option if you need to move items through the gate.
Tip #5 – Select the Alignment
Finally, you will want to look at is the alignment of the post plate and the gate plate. The alignment of these two parts can either be a straight line alignment or they can be offset. Select the alignment you find most pleasing aesthetically.
