Arm Type Details

This closer uses a track arm configuration rather than a traditional double lever arm. A track arm keeps the projection lower and provides controlled movement through the slide track assembly. For the 4040XPT-BUMPER application, the arm setup is intended for bumper use and supports push or pull side mounting with a maximum 110 degree swing.

Included Components

The closer package includes the LCN 4040XP series closer body and the track arm assembly for the bumper application. Installation uses standard mounting arrangements shown for the 4040XP series in the manufacturer literature.
