How To Choose The Best Weatherproof Combination Lock?
You'll also want to make sure that the material is strong enough to withstand force.
A weak lock is more likely to break under duress, so it's important to choose a material that can stand up to attempted forced entry.
Stainless steel and brass are the most common materials used for weatherproof locks. Both are incredibly strong, as well as resistant to rust and corrosion, making them ideal for use in harsh weather conditions.
So, either one would be a good choice for a weatherproof combination lock.
If you're looking for a weatherproof combination lock that can stand up to the elements, make sure to choose one with a high waterproof rating.
IP65 or IP66 waterproof rating is highly recommended.
IP65 waterproof rating: This rating means that the lock is protected from dust and low-pressure water jets. It's a good choice for combination locks that will be used outdoors or in other dusty or wet environments.
IP66 waterproof rating: This rating means that the lock is protected from dust and high-pressure water jets. If you often use your combination lock in very wet or dusty environments, consider an IP66 waterproof rated model.
Seal Of Approval
If you're looking to lock up something of high value, it's worth investigating locks that have been endorsed by one of the independent testing bodies.
These bodies put locks through a series of tests to assess their security and then give them a seal of approval accordingly.
The most well-known of these bodies are:
- CEN - the European standard
- Kite Mark - owned by the British Standards Institute
- Sold Secure - owned by the Master Locksmiths' Association
Each testing body has its own grading system, but in general, the higher the rating given to a lock, the more secure it is.
The shackle is the hoop-shaped section at the top of the lock that connects the two ends of the hasp.
When shopping for a weatherproof combination lock, it's important to pick a model with a shackle that is well-hidden or shielded.
A large, exposed shackle presents criminals with an easy opportunity to attack the lock with bolt cutters.
Locks with minimal shackle exposure, or ones that shroud part of the shackle within the body of the lock, are far more difficult to cut into and provide much better security.
