This video is to bring you a closer look at the Bommer 3023-3-633 Double Acting Spring Hinge .
The 3023 is the representative of the fact this is a half surface hinge and half surface is in the reference to the leaf that mortise and will attache to the door and in this case will be surface mounted to the face of the door.
The -3 is the representative of the size which you can see in the link called Template, is really not a dimension that you can take off of this hinge.
The 3" reference is actually a reference of how thick of a door this hinge is made to accommodate.
The 633 refers to the finish, satin brass finish.
Let's go back to 3023.
So you see you've got the leafs back here the door leaf pivots around like this and this is the jamb leaf.
You can see that you would push this leaf back, the jamb will set back here, you would attache this leaf to the jamb through these screws.
Once you get that attached to the jamb the hinge will look like this, your door set's into your packet here.
The 3" specifically means that this is intended for 3/4" to 1" doors.
Anything thinner or thicker will be a problem.
The door leaf simply surface mount to the face of the door, your door is gonna set into here. Screws are included.
This barrel will handle the spring aspect of the door loaded about this way and of course the back side is handled when the door is pushed on the opposite direction.
Really nice quality hinge by Bommer.
You can see the logo and right above that "Made in USA" and i am proud to represent them.
There's guide lines below this video for max weight.
These are small hinges even though they are not small technical.
With 2 Hinges: 35
With 3 Hinges: 39
Maximum Door Width
With 2 Hinges: 2'0"
With 3 Hinges: 2'8"
There is a link below this video to Installation Instructions and that shows in general how the 3023 series double acting spring hinge work.
If you have three hinges two of them need to be on top because that's the business end of everything what's happening with the mechanics of the double acting door all the weight it's gonna be born really on the top hinge on the top hinges so don't put that hinge on the middle.
If you feel that you are on the border line or something go with the 3th hinge because you ask each barrel and each spring to share the load because if you snap one of these by over tension it the hinge is irreparable plus these hinges also doing the job of keeping the door in a plumb.
One thing that is not very obvious in the extended description is the thickness of this material here between where the jamb will be and the packet of the door will go. That's important because if you take your width you will ultimate have to determine what is the net width of my door you have to determine that.
That would be based on how much margin to leave here and how much margin to leave between the door and the jamb or between two doors if is a double door.
Those conditions will vary depending on the thickness of the door, the width of the door will depend weather is single or double, the thickness of the door and how the edge of the door is treated is square or radius.
Per the Template this dimension is 9/32 so that's 0.28125 so you have to allow just over 1/4" just for the margin of the amount of hinge that you have between edge of the hinge and the jamb.
So you probably want to leave another 1/16".
You can have a door with just a square edge if you've got a single square edge door you want to make sure you leave enough room for the door to not be making contact with the jamb.
I've done this many times by all means reach out to me if you have any questions or you like to disuse it.
If you have thicker doors Bommers has larger version of these.
There is also a link to Technical Specifications below this which gives a lot of information specifically regarding setting the tension. On the spring there are arrows and that indicates the direction to increase the tension.
Tension rod it's gonna be included and tension pin included also inserted into the holes you reveal.
5 holes is what the instructions refers to on how much tension to set.
Screws are included painted to match.
Several different finishes are also available.
