US Tubular Lock or EU Mortise Lock?

US Tubular Lock or EU Mortise Lock?

There are notable differences between European mortise door lock systems and American standard tubular lever sets in terms of design, installation, and functionality. Here's a breakdown:

1. Lock Mechanism

  • European Mortise Lock: This system features a more complex mechanism, with the entire lock body installed inside a pocket (mortise) cut into the door edge. It includes a lock case where the cylinder and lever handle are integrated into a single, often larger, system. Mortise locks typically offer greater security and are commonly found in commercial or high-end residential applications.
  • American Tubular Lock: The tubular lever set is simpler, with the lock mechanism installed through a hole drilled in the door. The lever handle operates the latch via a spindle, and the locking mechanism (usually a thumb turn or key) is often integrated separately from the handle. This is more common in residential homes for interior and exterior doors due to ease of installation.

            

2. Installation Complexity

  • European Mortise: Installing a mortise lock requires precise carpentry work to cut a deep pocket into the door. This process is more labor-intensive and suited for solid, thicker doors.   15Mins installation
  • American Tubular Latch Lock: Tubular locks are much easier to install. A simple borehole through the door is sufficient for fitting the lockset, making it more accessible for DIY installation.  5Mins installation

3. Security Level

  • European Mortise: Generally provides a higher level of security due to its more robust construction and the deeper installation into the door frame. Mortise locks are often multi-point locking systems, securing the door at multiple points.
  • American Tubular: While secure, tubular locks tend to be less robust than mortise systems. They are typically used in residential settings where ultra-high security may not be as critical.

4. Aesthetic and Usage

  • European Mortise: Often used in higher-end projects or in countries with stricter building codes for enhanced security. Mortise locks offer a cleaner, more minimalist aesthetic because the lock body is concealed within the door.
                           
  • American Tubular: Common in North America, these locks are more visible on the door surface. Their ease of use and installation makes them a go-to for homeowners looking for a straightforward, functional design.

                            

5. Handle and Cylinder Configuration

  • European Mortise: The door lever, keyhole (or cylinder), and locking mechanism are often part of an integrated system, giving a seamless appearance.
  • American Tubular: In a tubular lever set, the door handle and locking mechanism are typically separate, often featuring a keyhole on one side and a thumb turn on the other.

6. Cost and Availability

  • European Mortise: Due to the complexity of the system, mortise locks are usually more expensive and may be harder to find in some parts of the U.S.
  • American Tubular: These locks are widely available and more affordable, making them a popular choice for DIY homeowners.

In summary, European mortise locks offer higher security and are more complex, while American tubular locks are simpler, easier to install, and suited for residential use.
