JELOSTONE Commercial Automatic Door Bottom, 5/8‘’W x 36''L x 1-7/8‘’H, Aluminum Automatic Door Bottom, Surface Applied or Semi-Mortise, with Neoprene Insert, JS-4131RL

• Drop Bar Seal Actuation:

  When the plunger contacts the jamb, the drop bar seal actuates from the hinge side first. This allows for multiple compression points, which helps in maintaining a tight seal between the door and the floor. This feature ensures that the door closes smoothly and tightly, preventing drafts and unwanted elements from entering the room.

• Low Closing Force:

  The plunger requires a low closing force to actuate the drop bar seal. This feature ensures that the door closes smoothly and quietly without any jerks or vibrations. The "L" at the end of all product numbers stands for Low closing force, indicating that the product is designed for smooth and quiet operation.

• End Plates:

  End plates are provided for all mounting applications. These end plates ensure that the automatic door bottom is securely mounted to the door, providing stability and durability.

• Net Length:

  All JELOSTONE Automatic Door Bottoms are provided in net length, which means they are supplied in their full length without any trimming. However, stock length automatic door bottoms can be trimmed up to 2", allowing for customization to fit specific door sizes.

• Certifications:

  This automatic door bottom is UL-certified and features functions to block the penetration of sound, air, smoke, and flames, meeting high standards for performance, safety, and environmental friendliness.
