Details: Pemko 411 Full Mortise Automatic Door Bottom

Automatic Door Bottoms

These automatic door bottoms consist of an aluminum case which surrounds a movable drop bar seal. The drop bar seal is actuated by a plunger which contacts the jamb as the door is closing, forcing the drop bar seal down against the floor or threshold.

When the plunger contacts the jamb, the drop bar seal actuates from the hinge side first allowing multiple compression points.
The plunger requires low "FeatherTouch" closing force to actuate the drop bar seal. The "L" at the end of all product numbers stands for Low closing force.
End plates are provided for all mounting applications.
Available in sizes ranging from 18" to 72"
All automatic door bottoms are provided net length.
Stock length automatic door bottoms can be trimmed as much as 2".

Non-Handed, Full Mortise

Smoother action positive seal mechanism. All Pemko automatic door bottoms consist of an aluminum case which surrounds
a movable drop-bar seal. The drop-bar seal is actuated by a plunger which contacts the jamb as the door is closing,
forcing the drop-bar seal down against the floor / threshold.
Most models are now available with nylon brush (NB) seals. The nylon filaments conform extremely well to irregular
surfaces such as carpet, stone and grout lines.
Especially over uneven surfaces, both PemkoPrene® (PK) and nylon brush (NB) provide excellent seals to keep out draft,
dust, moisture, insects, fumes, light, and sound.
All models (except #430 and #412) are non-handed and reversible. Installation is fast and easy because disassembly is
not required to change handing: simply flip the automatic door bottom and you've reversed the hand. The clean
symmetrical square-shaped case design also provides for even flush mounting.
The line includes models which can be mounted to either wood or hollow metal doors.
End plates are provided for all mounting applications.
All Pemko automatic door bottoms seal up to a 3/4" gap under the door except 420 and residential models which seal
1/2 maximum.
Available in any size ranging from 18" to 48".
Lead line available upon request; consult Customer Service for options on profiles.
The drop-bar seal actuation mechanism (all models) causes the drop-bar seal to always actuate on the hinge side first.
This feature prevents the seal from skidding along the floor / threshold while the door is being closed. Door hang up
will not occur.
All Pemko automatic door bottoms are provided NET length.
