Built to Keep You Safe

Every Mazuli bifold door is fitted with multi-point espagnolette locking as standard. Combined with internally beaded glazing and anti-lift blocks, our doors provide reliable day-to-day security straight out of the factory.

Internally Beaded

Glazing beads sit inside the property — glass cannot be removed from the outside

Anti-Lift Blocks

Shoot bolts and anti-lift blocks on intermediate panels prevent the doors being lifted from the track
