Shearlocks FAQs
What are the benefits of a hybrid lock over a standard electric lock?
Hybrid locks combine mechanical and electromagnetic mechanisms, offering stronger holding force and reliable unlocking even during power failure or mechanical wear. They also prevent misuse by automatically switching to mechanical mode when needed.
Can these locks be used on fire?rated or escape?door systems?
Yes—electromagnetic locks compliant with EN 13637 can be integrated into escape-route doors, provided they include safe-release features that ensure rapid exit during emergencies.
Do I need a specialist installer for electromagnetic locks?
Professional installation is strongly recommended. These locks require correct alignment, power supply integration, and compatibility with existing alarm or access-control systems. Our technical sales team can provide specification and installation support.
Can BM Steel locks be retrofitted to existing doors?
In many cases, yes. Hybrid and electromagnetic locks can replace standard locks if the door style and power supply allow. Some retrofitting may require drilling new mounting holes or installing power runs.
How long do stainless steel locks last in coastal environments?
Grade 316 stainless steel options are designed specifically for outdoor or coastal use and resist salt corrosion over long periods. Regular maintenance, like cleaning salt deposits, further prolongs service life.
