How do I know which Trilennium® lock system I need?

There are four multi-point locking systems within the Trilennium family - 3000, 3020, 3070 and 3500.

1. Check how many locking points are present - two, three or five?

• If two (one into the header and one into the sill), you most likely have a Trilennium 3020 Locking System.
• If three (horizontal deadbolts that lock into the inactive door panel or jamb), you most likely have a Trilennium 3000 Locking System or Trilennium 3070 Locking System.
• If five (three horizontal deadbolts, one into the header and one into the sill), you most likely have a Trilennium 3500 Locking System.

2. I have three bolts - do I have Trilennium 3000 Locking System or a Trilennium 3070 Locking System?

• Measure the width of the faceplate - is it 1" wide or 7/8" wide? If it is 1" wide - it is a Trilennium 3000 Locking System.If it is 7/8" wide - it is a Trilennium 3070 Locking System.
