Help understanding Dual Action Pivot Hinges

I want to hang a spring loaded door into my pantry. I want it to push open both directions and be able to stay open if I so choose.

I'm going to be hanging it in a doorway that already has ceramic tile over concrete floor.

I've searched for hinges that mount on the door jamb like regular hinges but none of these seem to be able to stay open, they only return to the close position.

Below are the only hinges I've found so far that do what I want them to do, but I don't understand the difference in these two, one comes with 'floor plate' the other comes with 'jamb' plate.

The pictures look the same but when looking at the templates for them there is a difference I just can't tell what it is. Could someone help me with this one?

Also am I going to have to cut out a chunk of the door for these cause I really hate to do that if I don't have to, or maybe I'm just not finding the correct hinges for my door.

It's a pretty heavy door I would guess, wood frame with a full frosted glass insert.

I'm looking for some input on trying to decide what type hinge I need and where on earth I can find what I'm looking for. At this point I'm not even sure what questions I need to ask.

Thanks in advance for taking your time to help me.


Spring Pivot with Floor Plate

Spring Pivot with Jamb Plate

 

There are dinning room door hinges that mount in the top of the jamb, and/or, I think in the door. All require making carefully sized openings to fit the hardware. But you should be able to find hinges, either locally is a good lumberyard(not big box), or on the net.

 

First, double action spring hinges with hold open exist (from butt to clamp flange forms of attachment). (The hold open feature is dependent on the weight of the door leaf.) A number of main line hinge manufactures produce them. If you can't find what you're looking for in one of the online catalogs, email customer or technical support.

The pivot with jamb plate is intended for a heavier door. The tang the rises at the back of the hinge mounts to a mortise in the hinge jamb. The pivot with floor is intended for a lighter door.

Since you're in the discovery stage two things that may plague you: door weight & square or radius styles (strike and/or hinge styles). Anyone that really knows what they are doing will ask both questions.
