STEP 22 - Automatic flush bolt for aluminium doors

Automatic flush bolts for double doors where two door leaves close against each other. A unique design allows opening despite a high preload.

STEP 21 and 22

The automatic flush bolts STEP 21 & STEP 22 have a unique design which facilitates the closing and opening of double doors.

Automatic flush bolts are normally assembled on the upper and lower part of the passive door leaf and are designed for the automatic locking of passive door leaves in a frame or threshold each time the active door is closed. The active door leaf is then automatically locked with a normal lock in the passive door leaf.

In the same way automatic flush bolts are designed to automatically unlock the passive door leaf each time the active door is opened.
