Choosing the Right Lock – what you need to know

Choosing the right lock for your caravan, camper trailer, toolbox, or any other application requires considering three key factors:

  • Usability
    Security
    Weather resistance

This blog post will explain everything you need to know about selecting the perfect lock from Dunn and Watson’s extensive range.

We offer locks suitable for various purposes. Whether you need them for interior or exterior applications, we have options in multiple finishes, colours, and locking mechanisms. Let’s delve deeper into the three crucial aspects to consider when selecting a Dunn and Watson lock.

2. Usability

Handle Action

Consider how the lock operates. Do you prefer a push, turn, or slam-action mechanism? It’s vital to choose a lock that’s easy and convenient to use for your specific application. There’s nothing more frustrating than struggling with a lock that doesn’t suit your needs.

2. Security

Key Locking

Dunn and Watson offer swing handles with integrated critical locks for the highest level of security. This option is ideal if theft is a major concern.

Locking vs. Non-Locking

Do you need a lock with a key or a simple handle? If security is paramount, a key lock is essential. For example, a toolbox used by a tradesperson would benefit from a key-locking handle. On the other hand, a non-locking paddle handle might be ideal if you’re building cargo drawers for your 4WD (which already has a central locking system) and want to avoid the hassle of repeatedly locking and unlocking.

3. Weather Resistance

It’s important to consider exposure to the elements. If your lock will be exposed to rain, dust, or other harsh weather conditions, weather resistance becomes a critical factor. You don’t want to find water leaking into your toolbox or dust accumulating in your camper trailer.

Weatherproofing Your Locks

At Dunn and Watson, we prioritise offering solutions that keep your gear protected from the elements. Here’s how our products excel in weatherproofing:

Whale Tail Series Handles

These handles boast a compression feature that effectively tightens the entire door seal, maximising weather protection. Additionally, they have a high-quality gasket around the shaft and a protected key barrel, providing a comprehensive barrier against the elements. Our Whale Tail series is available in black, white, and chrome finishes, offering both functionality and style.

Now that we’ve covered weather resistance, let’s take a closer look at weather seals and the importance the correct compression has on the quality of your seal.

How Much Compression Do You Need from Your Weather Seal?

Finding the right balance of compression is crucial for a weatherproof seal. While more compression is better, too much pressure can be just as detrimental as insufficient compression. Our various sealing solutions include foam tapes, D-seals, and pinch welds. While the minimum recommended compression is 30%, we suggest aiming for 40%. Here’s why:

Optimum Compression

Generally, 30% compression is considered the ideal level. However, real-world surfaces are rarely perfectly flat. With 30% compression, some areas might only experience 20-25% compression, creating a weak point vulnerable to water and dust ingress.

The 40% Rule

Aiming for 40% compression ensures even pressure across the entire seal, even on slightly uneven surfaces, to help prevent leaks and maintain a strong barrier against the elements. Exceeding 40% compression can damage the seal. Over-compression can crush the seal, causing it to lose its memory and effectiveness. So what happens if you do crush the seal or you the rubber gasket deteriorates over time?

How To Replace A Rubber Gasket On A Lock Once It Perishes

Many Dunn and Watson locks have a natural rubber gasket, perfect for internal applications like canopies or utes. However, natural rubber can deteriorate with exposure to sunlight and harsh weather, potentially cracking and allowing leaks.
The good news is, that replacing a worn-out gasket is a simple process:

  1. Remove the Old Gasket: Remove the existing gasket from the lock. The lock itself is designed for long-lasting durability.
  2. Apply UV Stable Silicone: Run a bead of UV-resistant silicone sealant around the base of the lock.
  3. Reinsert the Lock: Place the lock back into its designated cavity.

This quick fix provides a double benefit:

  • Outstanding UV Resistance: The UV-stable silicone ensures long-lasting protection against sun damage.
  • Enhanced Adhesion: The silicone creates a strong bond between the lock and the surrounding surface, improving weatherproofing.

Choosing the right caravan, camper trailer, or toolbox locks protects your valuable belongings. Understanding the different lock types, installation, and proper maintenance can significantly enhance your trailer’s security.
