Cut the Automatic Door Bottom To Size

It is always easiest to have the manufacturer cut your automatic door bottom to size.  If you do opt for a custom cut door bottom from the manufacturer then you will be able to trim up to 1" in the field.  If you buy the stock sized bottom then you will be able to trim up to 3" in the field to fit your door.  If you do choose to trim the door bottom yourself then make sure to only trim the side that does not have the black push button.

When deciding the width needed for your door bottom, you will need to measure from door stop to door stop and then subtract 3/32 of an inch.  If your door bottom is going to press directly against the door jamb then you will need to take that measurement instead, but still subtract 3/32 of an inch.  Now that you have the measurement required for your door bottom you can use either a chop saw or a table saw to make a perfectly straight cut.  Make sure to not cut the neoprene bottom at this point--this will be trimmed later on.

Placing the Spacer and Adjusting the Neoprene

There is a 1/2" thick white temporary spacer block inside your automatic door bottom.  This needs to remain inside the door bottom during the installation and remain opposite of the side with the black push button.

At this point you will need to adjust the neoprene with the spacer still inside the door bottom so that the neoprene is exposed an even 1/2" past the door bottom.  This will mimic how far the neoprene will drop when the automatic door bottom is attached to your door.

Planning For Attaching the Automatic Door Bottom

Close your door to prepare for attaching the door bottom.  With the temporary spacer still inside the door bottom, place the door bottom against the door so that the neoprene is resting on the floor.

The goal is to have the neoprene flush with the floor and the door bottom completely level.  To accomplish this you may have to adjust one of the screws on the top side of the door bottom.  For example, if the door bottom is level against the door and the left side of the neoprene is touching the floor, but the right side is not touching the floor, then the right side needs to be lowered.  Do this by loosening the door bottom's right top screw until the right side is flush with the floor while keeping the door bottom level the entire time.

Once you have adjusted the neoprene correctly and should now have a level automatic door bottom that can rest on the floor.  Using a pencil or marker, mark where the attaching screws will need to be drilled. 

Attach the Automatic Door Bottom

To make attachment easier you can pre-drill a pilot hole for the attaching screw.  Drilling a pilot hole will help ensure that when you do attach the door bottom you are attaching it in the correct spot.  Now remove that 1/2" block spacer from inside the automatic door bottom and use the 3 included attaching screws to attach the door bottom to the door.  With the door bottom attached and the door closed you will be able to clearly see how much of the neoprene rubber bottom needs to stay attached.  This measurement is typically about 1/4" past both sides of the automatic door bottom.>

Test the Automatic Door Bottom

Now that the door bottom is attached you can now test the operation of the door bottom.  The top screws that adjust the neoprene are accessible at all times so if there is a little drag when opening or closing the door then tighten the top screws a little to relieve the pressure.

Measuring and Cutting

The adjustable door stops can act as your only door stop or attach to the surface of your current door stop.  If you have purchased a adjustable door stop kit from us then it will arrive in three pieces which include a top piece and two side pieces. Decide on how you want your door stop to attach and then measure the distance along the top of the door for the width of the top piece.  Trim the top piece you received to fit along the top.  Using this newly trimmed top piece as a guide, measure from the floor to this top piece on each side of the door.  Now trim these side pieces to fit between the installed top piece and the floor.  You should now have three adjustable door stop pieces that are cut to fit tight within your door frame.

Planning For Attaching the Adjustable Door Stop

The adjustable door stop will arrive with the neoprene piece recessed into the metal frame.  Using the top adjustment screws you can loosen the screw so that the neoprene will extend 1/4" past the door stop's metal frame evenly along the length of the door stop.

With the door closed, you can first start with the top piece of door stop.  Position this first piece so that the neoprene rests comfortable against the closed door along the entire width of the door.  You will want the metal frame of the door stop to remain both level in relation to the door frame and tight against the door when the door is closed.  So keep a level on the door and make small adjustments to the screws on the top of the door stop.  Using a pencil or a marker, you can mark where you will need to screw in the attaching screws that were included with the product.  Repeat this step for both of the side adjustable door stop pieces until you have marked all the attaching screws for each of the three pieces.

Attach the Adjustable Door Stop

To make attachment easier you can pre-drill a pilot hole for the attaching screw.  Drilling a pilot hole will help ensure that when you do attach the door bottom you are attaching it in the correct spot.

Using the included attachment screws, you can now attach all three adjustable door stops to your door.  Start with the top piece first and then do either side next.  Double check when attaching the door stop that they are level with the door and the neoprene is flush against the door when the door is closed.

Test the Adjustable Door Stop

Once finished, you will need to test the opening and closing of the door in relation to the adjustable door stop.  The neoprene will need to be firm against the door when closed, but not severely compressed.  If the door is too difficult to close, then tighten the adjustment screws on the top of each adjustable door stop.  This will give your door a little more room to latch.  If the door seems as if it has move to rattle against the neoprene, then loosen the adjustment screws on the top of each adjustable door stop until the neoprene is flush with the door.  If you have followed all these steps then you will have successfully installed an adjustable door stop on your door.
