In the fields of mechanical engineering and furniture design, draw latches play a crucial role in ensuring the safe and efficient operation of various storage units. These unobtrusive but essential components are designed to keep doors or drawers securely closed and easily accessible when needed. The following will introduce the types and application fields of draw latch.
What is Draw Latches?
A draw latch is a piece of hardware that functions like an ordinary hinge that can be pulled open by hand. Draw latches are most commonly used on closed positions and enclosures to allow them to swing open without the need for any additional hardware or tools. The name "draw" is derived from the fact that these types of latches pull inwards towards themselves.
Draw Latches is a simple way to fasten doors, hatches, or panels. It has two parts: a hook or loop on one side, and a catch on the other side. Most draw latches have a spring-loaded lever—flip it to lock or unlock. Once closed, it stays shut. Draw latches are widely used in various industries, including furniture manufacturing, automotive, aerospace, and industrial equipment, due to their reliability and simplicity. Fornd, as a professional manufacturer of industrial cabinet locks and hardware, has many kinds of draw latches. There are many types of Fornd pull locks, including eccentric, adjustable and heavy ones.
Types of Draw Latch
Draw latches can be divided into different categories according to different classifications.
Fornd provides 5 types of draw latches, which are over-center latches, adjustable draw latches, lever-assisted draw latches, lever-assisted draw latches, rotary draw latches, concealed draw latches.
Over-Center Draw Latches
An over-center latch draw latch is commonly used where latching occurs in-plane. A pull handle is attached to the center of this type of draw latch, which allows it to be opened while still keeping its gate secure and closed while not in use.
The hinge pin is placed on the top of each side and can be welded in place after installation. Over-center draw latches are commonly used for gates that need to open perpendicular to their hinges while still preventing tampering by unauthorized persons when necessary.
Adjustable Draw Latches
Adjustable draw latches allow for changes in tension depending on what they're being used for. The arm of this type of draw latch is designed to be rotated around its hinge pin and then locked into place by a bolt or screw that allows for easy access when necessary.
Lever-Assisted Draw Latches
Lever-assisted draw latches work in similar ways to adjustable and over-center types of pull handles. This type of latch allows for tension applied to it to be changed depending on what they're being used for, but the hinge pin is placed at the bottom rather than along its arm.
The keeper is attached directly to the arm of this type of draw latch and can be detached from it by bending its tab until it's disengaged. This allows for quick access without having to remove a bolt or screw to open it, which is why lever-assisted draw latches are commonly used on gates that need to stay securely closed.
Rotary Draw Latch
Rotary draw latches provide a robust solution to secure panels with push to close convenience, offering concealed latching at one or more points of the application. Rotary latches are available in a wide range of compact mechanical and electromechanical designs made of durable materials suitable for any environment. Mechanical actuator solutions provide flexible security with hand or keyed operation, while electromechanical actuator options offer a hidden solution.
Concealed Draw Latch
This type of draw latch is commonly used when a design requires that the latching mechanism be hidden from sight. It has a metal hook on one side and a rotating arm with an enclosed center that can be pulled outwards through its pull handle, allowing for easy access. The hook keeper prevents the arm from being pulled out too far and accidentally unlatched.
Fornd provides 5 types of draw latches, which are over-center series latches, lever assisted latches, adjustable grip draw latches, rotary draw latches, and concealed draw latches. Each type of drawer latch also comes in different styles and models. Fornd also provides custom drawer latch services and offers free samples.

These pulls need to be able to endure harsh environments, including dust, moisture, and heavy loads, while also providing easy access for and operation.
