Screen Door Mortise Latch
Screen doors allow homeowners to enjoy fresh air and natural light without having to keep the whole house open, while also keeping insects and bugs at bay. One of the essential components of a screen door is the mortise latch, which enables the door to open and close securely. In this article, we will delve into what a mortise latch is, how it works, and how to identify and replace one if necessary.
What is a Screen Door Mortise Latch?
A mortise latch is a type of latch that is installed on the edge of a screen door, allowing it to open and close securely. It is composed of two parts: the lock body and the latch bolt. The lock body is usually installed in a recess, or “mortise,” in the edge of the door, while the latch bolt is mounted on the door jamb. A mortise latch usually has a thumb turn on the inside and a key cylinder on the outside, allowing the user to lock and unlock the door from both sides.
Types of Screen Door Mortise Latch
There are various types of mortise latches, including standard mortise latches, which are the most commonly used type. They are typically made of brass or steel and feature a rectangular or oval shape. Another type is the hook mortise latch, which have a hook-shaped latch bolt that engages with a strike plate. They are less common than standard mortise latches but are often used on sliding screen doors. Lastly, some mortise latches feature a combination of a hook-shaped latch bolt and a deadbolt, providing extra security.
Identifying a Screen Door Mortise Latch
Identifying a mortise latch can be a daunting task, especially if you’re not familiar with the different types of latches that are available. However, there are a few common characteristics that you can use to identify a mortise latch, such as the shape, size, and finish. Taking a picture of your latch and bringing it to a hardware store or online retailer can also help to identify the right replacement part.
Replacing a Screen Door Mortise Latch
Replacing a mortise latch can be a relatively easy DIY project, depending on your level of experience with screen door repairs. To replace a mortise latch, you will need to remove the old latch from the door and the jamb, measure the mortise size, and find a replacement that matches the dimensions and style of the old latch. Once you have purchased the replacement latch, you will need to install it by following the manufacturer’s instructions or consulting with a professional if necessary.
Common Problems with Screen Door Mortise Latch
The most common problem with screen door mortise latches is wear and tear, which can cause the latch bolt to become stuck or difficult to operate. Other issues include misaligned latch bolt, loose or broken screws, and damaged lock cylinders. These problems can be fixed by replacing the affected parts or adjusting the latch assembly.
Maintenance Tips for Screen Door Mortise Latch
To make sure that your screen door mortise latch lasts as long as possible, there are a few maintenance tips that you can use. Lubricating the moving parts with a silicone-based lubricant can help to reduce friction and wear. Tightening loose screws and adjusting the strike plate can also help to ensure that the latch operates smoothly. Inspecting the latch periodically and replacing worn or damaged parts can also help to extend the lifespan of the mortise latch.
