Understanding draw and toggle latches: types and applications
When you're designing equipment, the right fastening solution can make all the difference in performance, accessibility, and durability. Draw latches, also called toggle latches or tension latches. are a simple yet powerful way to keep panels, containers, and enclosures securely closed, even when vibration is present. In this guide, we’ll walk you through everything you need to know to choose the best draw latch for your application, covering:

Introduction to draw latches
A draw latch, as the name says, is a type of latch that securely holds two surfaces together. It consists of two parts: the clasp or hook, which is mounted on the surface, and the draw catch or strike plate, which is mounted on the mating surface. When the latch is actuated, it draws the two parts together tightly—hence the term ‘draw latch’. The clasp catches the strike plate and clamps down, creating tension and creating a tight seal.
The advantage to these latches is the strong, reliable connection created between the two surfaces, even withstanding vibration. They’re also easy to operate. If you’re using a draw latch on a tool box, for example, and one hand is occupied, you can open the latch quickly with your free hand to access what you need.

Types of draw latches
Not all draw latches are the same but all give you reliable performance.
Adjustable draw latch – with keeper
These toggle latches are typically used on containers, packaging, and industrial cleaning machines. Designed with a screwed catch for an adjustable gripping range to let you fine-tune the amount of tension or compression needed between the latch and the draw catch. The adjustable draw latch is available in stainless or mild steel, with padlockable or non-padlockable options.
Draw latch with keeper
Flexible over-centre draw latches feature a low-profile design with a concealed keeper mounted beneath the latch for a clean, streamlined look. The handle is made from black rubber, offering a non-corrosive, durable grip. Easy installation.
Draw latches
This over-centre draw latch features a smooth surface for a clean, aesthetic finish and operates using a draw hook mechanism. It secures in place by pushing the latch over its center point. Designed for light-duty use, it’s ideal for small containers, metal boxes, and light industrial cleaning machines. Available in steel, stainless steel or mild steel.
Side spring draw latches with keeper
The integrated spring provides flexibility in the pulling action, allowing for slight movement due to shock and vibration or thermal expansion while still maintaining a tight, secure lock. Spring draw latches are available in steel or stainless steel.
Link lock with keeper
The latch body includes a rotating disk and linkage mechanism. When the latch is closed, the rotating arm engages with the keeper and pulls the two mounting surfaces tightly together. As it moves past the center point, the over-center action secures it in place, even against vibration. Made of steel.
Wire loop draw latch & strike
The ergonomic design features a wire loop as the connecting link between the latch and the strike. The wire loop hooks over the lip of the strike plate when engaged to provide a tight seal. The low profile is light weight and made of mild or stainless steel. Draw catches and strikes sold separately.

Materials used for draw latches
How do you choose the material for your toggle latch? That depends a lot on the environment the latch will be exposed to. Here’s a breakdown of common materials used to make toggle latches to help you make your decision.
Mild steel
If budget is your priority, mild steel is a good starting point. Mild steel is mostly composed of iron with a small amount of carbon — typically between 0.05% to 0.25% carbon by weight.
It's ideal for light- to medium-duty applications where the latch won't be exposed to moderate moisture. Without coating, it’s prone to rusting. Mild-steel draw latches are suitable for indoor machinery panels, office equipment or packaging machines.
Stainless steel
Stainless steel is an iron-based alloy that contains at least 10.5% chromium by weight — and that’s the key ingredient that gives it its signature corrosion resistance. Use stainless-steel draw latches when corrosion resistance, durability, and long-term performance are critical. This is the best choice for demanding environments, indoors or outdoors. Stainless steel draw latches are often the most reliable option where failure or corrosion would be costly or dangerous.
Steel
Steel sits between mild and stainless in terms of strength and corrosion resistance. It’s stronger than mild steel and suited for heavier-duty applications, such as industrial equipment, transport cases, or structural panels, especially where strength is more important to you than appearance or environmental resistance. If you're dealing with high loads, carbon steel is a solid choice — just not for corrosive or damp environments.
Draw latch uses and applications
Draw latches provide strong, vibration-resistant closure, which makes them ideal for multiple applications:
● Toolboxes – secure closure with easy access
● Industrial and commercial enclosures – panels, access doors, and hatches
● Packaging systems – crates and containers
● HVAC and electrical cabinets – tight sealing with vibration resistance
● Light machinery – covers, service panels, and guards
● Transport containers – keeps lids or equipment boxes closed during transit
● Marine and outdoor equipment – stainless-steel draw latches resist corrosion in harsh environments
● Automotive panels – lightweight latches for vibration-heavy use
● Consumer products – cases, appliances, or electronics

How to choose the right draw latch
The draw latch you choose should depend on several key factors specific to your application.
1. Vibration and movement
If you’re using the draw latch in an environment where you can expect repeated shock and vibration, your best bets are our spring-loaded draw latch or one of our over-centre locking latches to maintain a secure hold without loosening.
2. Adjustability
If your latch must accommodate variable tolerances or compress a gasket, go with our adjustable draw latch to control tension and ensure a reliable seal.
3. Space
In tight spaces or on visible surfaces, one of our low-profile draw latches offer a cleaner look and reduces snagging risk.
4. Security
If you need to prevent unauthorised access, choose our adjustable draw latch with the padlockable option.
