Door latch

Product Description

A door latch is a fundamental mechanical device used to secure doors and keep them closed, consisting of a movable bolt or tongue that engages with a strike plate on the door frame. This premium 2.5-inch tubular door latch is the most common type for internal residential doors, offering functionality, reliability, and a sleek modern aesthetic. Whether installing a new door or replacing an old latch, this complete unit provides a smooth, secure, long-lasting solution for your home.

What is a Tubular Door Latch and How Does It Work?

This tubular latch is a cylindrical mechanism installed within a mortice cut into the edge of the door. It features a spring-loaded tapered bolt, often called a tongue. When the door is closed, this tongue extends into a strike plate on the door frame, holding the door shut. To open, turn the handle to retract the tongue, allowing the door to swing freely. The tapered design allows the door to be pushed or pulled closed without using the handle, automatically latching shut as the door meets the frame.

What Are the Key Features of This 2.5″ Latch?

The case size is 2.5 inches, a standard for most modern internal doors. Material is durable, corrosion-resistant stainless steel with a premium satin finish. The bolt type is spring-loaded and tapered for smooth, quiet operation. The backset is the distance from the door edge to the center of the handle spindle, typically 45mm or 60mm for this case size. The faceplate is a stylish, rounded rectangular design that sits flush with the door edge for a clean, professional finish.

How Easy Is a Tubular Latch to Install?

Installing a tubular latch is a common DIY task requiring basic woodworking skills. The latch installs within a mortice cut into the door edge. A hole is drilled from the door face to accommodate the handle spindle. The latch inserts into the mortice, and handles attach on either side connected by the spindle. The provided strike plate installs on the door frame to receive the latch bolt. All necessary fixings are included.

Where Are Tubular Latches Used?

This latch is most commonly used for internal doors where a lock is unnecessary, such as hallways, living rooms, or offices. While it secures the door closed, it is not a security lock. For rooms requiring privacy, like a bathroom, this latch can be used with a privacy lock mechanism. For enhanced security, a dedicated locking solution is recommended.

How Do I Choose the Right Latch for My Door?

First, measure the backset—the distance from the door edge to the center of the handle hole. Common backsets are 45mm or 60mm for a 2.5-inch latch case. Ensure the case size fits the depth of your door edge. The 2.5-inch case is standard for typical internal doors of 35mm to 44mm thickness. Finally, consider material and finish to match your door hardware.
