Institutional Custodial Security

Correctional and detention facilities require heavy-duty mechanical cylinders that withstand extreme physical violence and tampering.

Dual High-Tensile Bolt Anchorage

  • Solid Steel / Brass Body: Heavy oval profile envelope anchored via two M6 high-tensile through-bolts withstanding $>30\text{ kN}$ axial pulling.
  • Tamper-Proof Keyway: Restricted paracentric keyway preventing insertion of foreign contraband or picking tools.

Frequently Asked Engineering & Selection Questions

Q1: Why are oval cylinders preferred in detention facilities?

They are anchored from behind with two heavy M6 steel bolts that resist over 30 kN of pulling and sledgehammer attacks.
