    Automatic Door Bottoms utilize a concealed flat spring mechanism and plunger. When the door is closed, a brass plunger is compressed to automatically lower the seal, starting from the hinge side first. This motion ensures a smooth usage even on an uneven surface and prevents drag. The seal is automatically raised upon opening. These automatic door bottoms have been successfully tested through 5 million cycles!

    Automatic Door Bottoms are available with three mounting options: Surface Mounted, Semi-Mortised and Fully Mortised. A surface mounted application can be applied without removing the door from its hinges. For a semi-mortised, if the rabbet in the door is cut-out already, the door does not need to be removed. For a fully mortised application the door should be removed before starting. 

    STEP 1: SIZING YOUR DOOR BOTTOM

    Once your door is ready for installation you need to determine the size required for your door bottom:

    • For a Surface Mounted Application: Measure the distance between the two stop moldings, or if a perimeter door gasket is applied, measure the distance between the two installed gaskets, then minus 1/8-1/4"” (.125”) from the total distance. That is the size needed for your door bottom.
    • For a Semi-Mortised and Fully Mortised Application: Measure your door from side to side; that is the measurement needed for your automatic door bottom.

    For visual presentation see How to Measure for an Automatic Door Bottom.

    Once you have determined the size needed, if necessary, trim your door bottom. Use a chop saw or table saw to create a perfectly straight cut.

    Note, Only trim opposite the actuating plunger, brass nut. (Trimming from the brass nut side will ruin your ADB).

     

    How to Install an Automatic Door Bottom- Figure 1You can trim from the edge up to one inch of the screw in the side wall of the ADB.
     

    STEP 2: PREP FOR ATTACHING AUTOMATIC DOOR BOTTOM

    How to Install an Automatic Door Bottom- Figure 3Surface Mounted and Semi-Mortised models need to be applied to the push side of the door only (the side with the door stops). The actuating plunger needs to be applied to the hinge side of the door for all applications.

    Place the automatic door bottom against the door

    Once you have the automatic door bottom leveled and positioned correctly, with a pencil or marker mark where the attachment screws need to be drilled.

    STEP 3: ATTACHING THE AUTOMATIC DOOR BOTTOM

    How to Install an Automatic Door Bottom- Figure 4

    To make installation easier you can drill a pilot hole which will ensure you attach the door bottom to the correctly marked spot. With the screws provided, screw in the automatic door bottom.

    In some models, a plate is provided for the hinge side of the frame. This will protect the door frame from getting worn down by the actuating plunger. If provided, attach to corresponding point on the frame.
     

    STEP 4: TESTING YOUR AUTOMATIC DOOR BOTTOM

    How to Install an Automatic Door Bottom- Figure 5Now that the door bottom is attached, test the door bottom by opening and closing the door to ensure there is a full seal. If the seal does not come down far enough twist the brass nut out, if it seals too tight twist the brass nut in.

    Once you have followed through with all the instructions your Automatic Door Bottom is good to go! Enjoy years of quality sound, draft and light infiltration control with your new door bottom.

    Not worth the premium

    Comments about Zero #361, Automatic Door Bottom, Surface Mounted, Heavy Duty, Sponge Neoprene Seal, 1" Drop

    While I'm still hopeful that the product will help reduce noise coming from my kitchen, the finish work is not what I expect for the price. Trademark was straightforward in purchase communication and updates pre and post shipping. The mounting holes still had burrs, there were aluminum shavings remaining, it was scratched before arriving, and the set screw countersunk looks to have been done by an amateur. For the good, the length cut is square and finished nicely, the interior mechanism operates as expected, and the light spring is a neat option.

    My office is right across the hall from the building restrooms, so I hear every flush and hand dryer. Ugh! But not anymore, thanks to this door sweep. And installation was easy—Thank you TM Hardware!

    I would not order again

    Comments about Zero #361, Automatic Door Bottom, Surface Mounted, Heavy Duty, Sponge Neoprene Seal, 1" Drop

    Sent me the wrong length after 2 months and then strung me along for another month and then said it would take yet another. I asked and got a refund but being strung along for months is just ridiculous. If you can't provide the product then offer an alternative or provide a realistic time estimate.

    It took me a while to track this product down, but once I found it the company knew exactly what I needed and got them on order. The new ones are even better then the older ones. Overall I'm extremely happy with the product and the service.

    An excellent product. Performs and installs as advertised.

    Comments about Zero #361, Automatic Door Bottom, Surface Mounted, Heavy Duty, Sponge Neoprene Seal, 1" Drop

    Had a minor problem with the rubber seal inside popping out of it's groove and distorting. Disassembled the unit & put the rubber seal back in it's place and all is well now.
