Please find this product at http://absupply.net/ This video is to bring you a closer look at the National Guard 422N. This is an Automatic Door Bottom. Lets start at the beginning. 422 is representative of the type of automatic door bottom this is. The 422 makes it a mortised type. This is something that is intended to be mortised into the bottom of the door. It also makes it heavy duty. This is a substantially large automatic door bottom as far as automatic door bottoms go; this is a pretty big one. The N means neoprene; it's a very large substantial neoprene insert that is in there. Automatic door bottoms with a neoprene insert considered heavy duty. Maximum drop of 7/8" which we will get to in a moment. This is available only in this mill finish because this mortise style is of course concealed and you would never see it when it is fully installed they make it in only one finish and is considered a mortise mount. Use with a threshold for maximum sealing capability. Now, lets start from the beginning on automatic door bottoms. What is an automatic door bottom? In short, it is a device that seals the bottom of a door when the door is closed. It does that quite simply by a very simple mechanism. Now you will notice that on this end of the door bottom there is this item. We will call that the plunger and it is projecting out a little bit there, it has a slotted sort of drive on it. The other end, you will take note that it does not have that. When it is installed into the end of the door, the plunger is installed onto the hinge side of the door. The door is pushed closed, this will make contact with the jamb and when it does so, it is compressed and it is the action of the plunger being compressed that forces the bottom to drop. Now what you are seeing here is the natural sort of operation of an automatic door bottom meaning that when it is depressed, it doesn't drop straight down, but what actually happens is when it is depressed, the one end comes down and my thumb will represent it making contact with the sill, restricting it and when this is restricted from dropping down any further, it will drop the other side down. So as I hold it, it will make the other side drop down. If I restrict the opposite side, it forces the other side to come down. So what happens is the item kind of drops like a guillotine. One side will make contact and the rest will contour down, making it quite elegant because it will seal to a sill that may not be level or a door that may not be plumb, not a way situation but a condition by which the sill may not be exactly level. That is how these go. The amount of projection of the bolt or the plunger is directly related to the amount of drop, again a maximum drop of 7/8". If I turn that counter clockwise, it pulls it out more and that means I will be able to achieve a greater amount of drop on there. So what happens is this plunger is connected to a flat spring and when that plunger is pushed in, it forces the flat spring to belly. It is the bellying action of the flat spring that pushes the automatic door bottom down. Lets continue by looking at the link to the product brochure which is below this. The product brochure shows this and its sister products. First of all, I need to point out to you that on the product brochure is a feature of the 422N. So you've got the really healthy amount of nylon seal that is here, pardon me neoprene seal that is here. What you see over here at the tip of my finger is an inserted brush seal and that makes contact with the inside face of the unit helping to retard the transmission of air up and through the channel and out the other side. That is a very common feature that you will find on automatic door bottoms that are considered heavy duty. You can see that there is a hollow tube type neoprene that is there which is the 522N. You know that I like the hollow tube style because I feel like I get better total surface area coverage when that entire tube flattens down. I might opt for that model when I know that I have a smooth top threshold. By all means if you are in the business of making a living installing doors etc. familiarize yourself with National Guard. They are a leader with excellent customer service and even better technical support and good shipping lead times as well. Any questions on the National Guard 422N Automatic Door bottom with mortise type heavy duty or any other National Guard product, please feel free to reach out to us. Thank you.

Written by Dr. Seuss and the basis for the latter 1946 Oscar-winning film, "Hitler Lives."' Reupload of a previously uploaded film with improved video & sound. Public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Allied-occupied_Germany The Allied powers who defeated Nazi Germany in World War II divided the country west of the Oder-Neisse line into four occupation zones for administrative purposes during 1945--49. In the closing weeks of fighting in Europe, United States forces had pushed beyond the previously agreed boundaries for the future zones of occupation, in some places by as much as 200 miles. The line of contact between Soviet and US forces at the end of hostilities was temporary. After two months in which they had held areas that had been assigned to the Soviet zone, US forces withdrew in the first days of July 1945... American Zone of Occupation The American zone consisted of Bavaria and Hesse in Southern Germany, and the northern portions of the present-day German state of Baden-Württemberg. The ports of Bremen (on the lower Weser River) and Bremerhaven (at the Weser estuary of the North Sea) were also placed under American control because of the American request to have certain toeholds in Northern Germany. The headquarters of the American military government was the former IG Farben Building in Frankfurt am Main. Beginning in May 1945, many of the American combat troops and airmen in and around Germany were sent back to the United States based on their Advanced Service Rating Scores. Some of the experienced officers and non-commissioned officers were selected to be sent to the Pacific Theater of Operations for the proposed Invasion of Japan, but most of those men who had served the longest in combat were discharged from the U.S. Army, the Army Air Forces, and the U.S. Navy upon their returns home. Following the Surrender of the Japanese Empire in mid-August 1945 -- by its acceptance of the Potsdam Declaration -- a higher percentage of soldiers, airmen, and sailors were granted their final discharges from service. The official signing of the surrender took place on Septermber 2, 1945, but the hostilities had ended weeks earlier. Berlin While located wholly within the Soviet zone, because of its symbolic importance as the nation's capital and seat of the former Nazi government, the city of Berlin was jointly occupied by the Allied powers and subdivided into four sectors. Berlin was not considered to be part of the Soviet zone. Governance and the emergence of two German states The original Allied plan to govern Germany as a single unit through the Allied Control Council broke down in 1946--1947 due to growing tensions between the West and the Soviet Union... The complete breakdown of east-west allied cooperation and joint administration in Germany became clear with the Soviet imposition of the Berlin Blockade that was enforced from June 1948 to May 1949. The three western zones were merged to form the Federal Republic of Germany in May 1949, and the Soviets followed suit in October 1949 with the establishment of the German Democratic Republic (GDR). In the west, the occupation officially continued until May 5, 1955, when the General Treaty ("German: Deutschlandvertrag") entered into force... When the Deutschlandvertrag became law, the occupation officially ended, the western occupation zones ceased to exist, and the high commissioners were replaced by normal ambassadors. West Germany was also allowed to build a military, and the Bundeswehr, or Federal Defense Force, was officially established on November 12, 1955. A similar situation occurred in East Germany... the Soviet Union concluded a state treaty (Staatsvertrag) with the GDR on September 20, 1955. On March 1, 1956, the GDR established a military, the National People's Army. Despite the grants of general sovereignty to both German states in 1955, full and unrestricted sovereignty under international law was not enjoyed by any German government until after the reunification of Germany in October 1990...
