Understanding the Differences
The PRO 400 stands out as the stronger option, primarily due to its enhanced resistance to destructive attacks. While both locks utilize a disc-detainer locking technology and offer excellent picking and bumping resistance, the PRO 400 is designed with reinforced features that provide superior protection against drilling and snapping.
According to TOKOZ’s product listings, the PRO 300 is classified as RC3, while the PRO 400 is rated RC4. This classification indicates the level of security each lock provides, with the PRO 400 being the more robust choice for high-risk environments.
When to Choose Each Lock
If you are looking for a reliable and cost-effective solution for residential security, the TOKOZ PRO 300 is an excellent choice. It offers high-quality protection suitable for most home entrances.
On the other hand, if your property is at a higher risk of break-ins or if you are securing valuable assets, the PRO 400 is worth the additional investment. Its reinforced design and higher resistance ratings make it ideal for businesses and properties that require top-tier security.
Final Thoughts
Regardless of which lock you choose, proper installation is crucial. Ensure that the cylinder does not project more than 2–3 mm beyond the protective fitting to maintain optimal security. Both the TOKOZ PRO 300 and PRO 400 provide excellent options for safeguarding your property, so assess your needs and make the best choice for your situation.
