Trilennium® delivers 3x the strength, 3x the security and 3x the performance
with one multi-point locking system, resulting in maximum peace of mind and
homeowner satisfaction.

Operating as one, all three bolts engage when the door is closed, fighting
deflection even when the door is unlocked.

One movement of the key or thumbturn activates all three bolts, drawing the door
into perfect alignment with three true deadbolts that cannot be compromised.
Plus, it’s easy to use. Just one turn of the lever disengages all three bolts for easy
operation time after time.

Trilennium’s superior strength works when others fail, achieving
the industry’s highest ratings for structural and forced entry testing. A solid,
one-piece I-Beam runs the full length of the lock. This not only increases the
strength and precision of the lock, but also strengthens the door edge,
preventing warping over the life of the panel.
