US Security Grades and Certifications We Work To
For ensuring superior security, we adhere to the highest US standards. Our work in Jacksonville upholds ANSI/BHMA and UL437 certifications, ensuring robust protection for your property. We recommend Grade 1 locks for high-security needs like Downtown riverfront high-rises and Ortega estates. These locks offer top-tier durability and resistance. For most residential needs, Grade 2 provides reliable protection, especially for doors around Five Points and Avondale. We typically upgrade from Grade 3, the standard builder-grade, to enhance security.
UL437 certification ensures high-security cylinders that resist drilling and picking, perfect for San Marco and Ortega. Restricted keyways, like Medeco, offer patented key control, preventing unauthorized duplication.
Here's a quick reference:
| Grade | Usage | Locations |
|---|---|---|
| 1 | High security | Downtown, Ortega |
| 2 | Residential heavy-duty | Riverside, Avondale |
| 3 | Basic builder-grade | Typically upgraded |
