Best suited to perimeter & internal rated pairs of hollow metal doors where alternative locking hardware may be unsuitable.
Correct hardware specification on plain meeting and rebated pairs of doors is vital to ensure that integrity is maintained. Flush bolts provide a means to ensure fixed leaves are held in position (manual) or released (automatic) when the active leaf of a pair of doors is opened.
