The 410 Series holders and stops offer the industry’s widest variety of functions, base materials and finishes to fit all medium- to light-duty applications. The perfect combination of form and function, they offer effective door control and a low-profile design. Each model is constructed so that the channel is encased within the door and the jamb bracket is mortised in the frame. When the door is open, the arm and jamb bracket are visible. Conversely, when the door is closed, the entire holder is completely concealed.
The models can be used with most surface-applied door closers. The provided templates allow for variable mounting positions, ranging from 85° to 110° of opening. These templates are designed for installation in almost all types of doors, including doors with conventional butt-type hinges or specialty hinges.

3) How do you determine left hand versus right hand operation?
Stand on the pull side of the door. If hinges are on your right, order right hand. If hinges are on your left, order left hand. Specify handing when ordering as units are not reversible in the field.
4) What finishes are available for the 410 Series?
Standard finishes include aluminum, dark bronze, and satin chrome. Custom finishes may be available on special order. Finish should coordinate with existing door hardware for consistent appearance.

Complete unit includes the overhead holder mechanism, mounting hardware, and installation template. Verify all components are present before installation. Additional accessories like electromagnetic release may be ordered separately.
7) Where does the 410 Series mount on the door frame?
Mounts concealed in the head frame above the door. Requires sufficient frame depth and clearance. Use manufacturer template for precise positioning. Frame must be structurally adequate to support holder and door loads.
