M2M4Bradbury's M2M4 is a high-security doorset, certified by the LPCB to LPS 1175 Security Rating 4.

The M2M4 range of steel doors offers single, leaf and a half, and double outward opening doorsets, and single inward opening doorsets.

M2M4 doors are suitable for all personnel, fire exit, access control and utility applications.

To achieve LPCB certification, the M2M4 security doors were subjected to an attack test, simulating experienced attempts of forced entry. Tools used in the SR4 testing include a disc grinder, felling axe, hole saw, jigsaw, sledgehammer, and plate shears.

The wide choice of available hardware and options enables M2M4 doors to be tailored to individual customer requirements.

These doors are also available with the added benefit of an FD240 fire rating, under the CERTIFIRE scheme, providing 240 minutes of fire resistance.

Offering Bradbury's highest level of security, the M2M4 door has never been successfully broken into.
