Precision, Power, and Speed: Southco R2 and R5 Panel Fastening Draw Latches

When structural integrity meets speed and simplicity, you get Southco’s R2 and R5 Panel Fastening Draw Latches—innovative fastening solutions designed to join large panels quickly and securely in even the toughest environments. These latches offer the perfect combination of high strength, concealed design, and ease of use, making them essential hardware across a wide range of industrial applications.


Fast, Strong, and Sealed

The R2 and R5 draw latches feature a pull-up action that engages the panels tightly and compresses gasketing to create an airtight or watertight seal. This is crucial for protecting sensitive internal components from environmental contaminants like dust, moisture, or chemicals.

With less than one full turn of a hex wrench, these latches allow for fast and secure fastening or release. Once secured, they are completely concealed within the panel, contributing to a clean, tamper-resistant finish.


Key Features

  • Tool-activated operation: Assemble or disassemble structures using only one hex wrench
  • Airtight/watertight sealing via pull-up latch compression
  • High-strength concealed joint design
  • Fast, reliable panel connection and release
  • Mounting and material options to match various panel constructions and environments

Product Spotlight: Southco R4-EM-9 Rotary Locks

Southco’s R4-EM-9 Series electromechanical rotary locks provide key features that are ideal for security monitoring on applications such as buses, RVs, point of sale product enclosures, and data storage/server enclosures. R4-EM-9 series locks are controlled by a microprocessor that provide the attached signal device with the lock status. For example, if the lock is connected to an electronic keypad the screen will show if the latch is open or locked.

R4-EM-9 Lock Settings

The R4-EM-9 rotary lock offers both auto relock or delayed relock settings.

Auto Relock

In this mode a signal device (such as a computer or keypad) is used to unlock the latch. When the door is pushed back to the closed position the latch automatically locks.

Delayed Relock

Like auto relock mode, the delayed relock mode uses a signal device to release the latch and open the door. However the delayed relock mode differs in that the signal device must also be used when closing the door. When the door is pushed shut the user must then use the signal device (keypad, computer, etc.) to reengage the lock and secure the door.

Additional R4-EM-9 Lock Features

  • Simple two-hole installation
  • Minimal power draw (energy efficient)
  • Accommodation for existing control systems
  • High electromechanical release load – (latch has a high resistance to breakage when force is applied.)
  • Kick-out spring door assist (optional for delayed relock versions)

R4-EM-9 Part Configuration

Part configuration for the R4-EM-9 series electronic locks is relatively simple. By referring to the figure below you can identify the complete part number by selecting a trigger style and base mounting style. For additional details checkout the Southco R4-EM-9 rotary lock spec sheet.

What is a Draw Latch?

Draw Latch Description

Draw latches operate on the principle of drawing two items together using tension. The main components of a draw latch assembly are the blade (a hooked plate or a wire formed loop), the keeper (a hooked plate that receives the blade), and the hinge. The tension is created when the blade is hooked to the keeper and clamped down. For typical draw latches the tension is released when the latch is rotated to a vertical positon and is applied when the latch is rotated to a horizontal position.

Draw Latch Styles

Despite shared functionality, draw latches come in many different styles.

Draw Latch Applications

Because of the simplicity and effectiveness of draw latches they are utilized in a large number of applications. Draw latch applications include HVAC systems, exhibits, signs, agricultural equipment, industrial machinery, trucks, and lawn/garden equipment.

What is a Grabber Catch Latch?

A grabber catch latch is a push-to-close style latch which locks when the hooked keeper is inserted into the catch and the cam rotates into the hook of the keeper creating the necessary tension to secure the latch in place. Grabber catch latches are typically actuated (unlocked) using electronic switches or pressure (pushing or squeezing the latch to release the cam). Grabber catch latches can be used on swinging or sliding doors and can be mounted to any orientation as long as the keeper and catch orientation correspond.
