When it comes to securing doors, panels, or lids, draw latches are an essential component. They provide a secure closure and are commonly used in various applications, from industrial machinery to household appliances. Choosing the right draw latch involves understanding your specific needs and the different types available. This blog will walk you through the key considerations in selecting the perfect draw latch for your requirements.

What is a Draw Latch?

A draw latch is a mechanical device that joins two objects together by pulling them close and securing them in place. It typically consists of a lever, a catch, and a base plate. When engaged, the latch provides a tight seal, preventing accidental openings and enhancing safety. Draw latches are commonly used in applications requiring frequent access, as their design allows for easy engagement and disengagement.

Key Factors to Consider When Choosing a Draw Latch

Material

Whilst other businesses will manufacture draw latches from Aluminium and plastic, Protex draw latches are manufactured using stainless steel and mild steel with a zinc finish. Stainless steel draw latches are ideal for applications in harsh environments with stainless steel offering superior corrosion resistance, strength, and longevity. These stainless steel draw latches are perfect for outdoor use or industries like marine and aerospace. Zinc-plated draw latches also protect the latch from environments with a small amount of exposure to the elements but often aren’t cost-effective for outdoor use.

Type of Draw Latch

There are several types of draw latches, each with unique features and benefits. The most popular types of draw latches are standard draw latches, quick-release draw latches, adjustable draw latches and spring-loaded draw latches. Depending on the application, you’ll need to think about the type of draw latch that suits your requirements. For example, if a draw latch is frequently opened and closed, then a quick-release draw latch would be a great option.

Load Capacity

Understanding the force your draw latch will need to handle is critical. For industrial or heavy-duty applications, opt for high-strength latches capable of withstanding significant loads. On the other hand, lightweight latches are a good fit for less demanding uses, such as small cases or enclosures.

If you search the draw latches on our website, you’ll find the ultimate tensile strength (UTS) of each latch to help with decision-making. However, please be advised that we suggest approximately half UTS for a safe working load

Applications of Draw Latches

Draw latches are incredibly versatile and find use across a wide range of industries:

  • Transport and Freight: Securing cargo doors, containers, and storage compartments.
  • Electronics: Enclosures for sensitive electrical components and testing equipment.
  • Construction and Industrial Equipment: Fastening heavy-duty machinery panels and access doors.
  • Consumer Products: Used in toolboxes, cases, and other portable equipment such as music equipment.
