This product is a device that automatically closes a fire door using the spring force of the closer body and an air brake when the smoke and heat detector-linked smoke closer's holding function is disengaged. When fully closed, the door is pulled towards the three sides of the door frame on the passage side by inclined plates and rollers mounted at the top and bottom of the door, ensuring a tight fit against the frame. If you wish to keep the door closed for any reason, pulling it out from the pocket will disengage the smoke closer's holding function, causing it to close. 【Features】 ■ Custom-made to fit the width of the sash and door dimensions ■ Uses Smoke Closer D-24-1A for constant opening ■ Equipped with a re-lock prevention mechanism (reset is manual) ■ Made with iron rails and iron door wheels ■ Available in left or right configurations *For more details, please refer to the PDF materials or feel free to contact us.
