It clips over both inside handles, so it works even on French doors that open outward.

  • Both handles, locked togetherOne hook drops over each interior handle and the pin fixes the width. Neither handle turns, so neither leaf can be levered open.
  • Works on doors that open outIt holds the two handles to each other, so it never needs the floor or the frame. Outward-swinging French doors, where a floor brace is useless, are exactly where this one works.
  • Sets by pin, not by toolsA row of slots along the bar sets the width, so you match it to your handles by hand. Both leaves need an interior lever or knob at roughly the same height.
  • On and off in secondsLift it off to use the doors, drop it back on when you come in. Nothing is drilled or screwed into the doors, so a rental stays exactly as you found it.

Why this door gets skipped

Two doors, and nothing solid in the middle.

Most door hardware assumes one door in a solid frame. A deadbolt throws into a stud. A floor brace pushes back against a shove. French doors break both assumptions: there are two leaves, they meet each other in the middle instead of a post, and on plenty of homes they swing outward, which puts the whole idea of a floor brace on the wrong side of the door. So the pair keeps the handle set it came with, and that is usually where it stays.

The useful thing about a pair of doors is that each one is standing right next to something solid. The other door. Tie the two interior handles together and neither one can rotate. A lever that cannot turn cannot pull its latch back, and a leaf that cannot move cannot be levered away from its partner. That is the whole idea, and it is why a bar between the handles does something a bar on the floor cannot do on an outward-swinging pair.

It also means the doors have to cooperate. Both leaves need an interior handle or knob, roughly level with each other, or there is nothing for the two hooks to sit on. Step over and look at yours before you order. That one detail decides whether this works on your doors.

Each door is standing next to something solid. The other door.

In or out, same job

A floor brace needs the floor. This needs the other door.

Braces and bars push against something: a track, a jamb, the floor. That works on a door that opens inward. French doors that swing outward give a brace nothing to push against, because the force you want to stop is pulling the leaf toward the yard, not shoving it into the room. A lot of patio pairs are hung that way, and their owners usually find that out after the box is open.

This bar pushes against nothing. It hooks over both interior handles and pins them at a fixed width, so the two leaves hold each other and swing direction stops mattering. It touches no part of the frame or the threshold, and it comes off in one motion when you want the doors open.

Setup

On in seconds, off just as fast

1

Check the handles

Stand inside with the doors closed. Both leaves need an interior lever handle or knob, sitting at roughly the same height, with a clear gap between the two.

2

Set the width

Move the pin along the row of slots until the bar sits snug between the two handles, not stretched and not slack. That is the only adjustment there is.

3

Hook it on

Drop one hooked end over each handle from inside. The bar holds itself there. Nothing screws in and nothing touches the frame.

4

Try the doors

Push and pull on both leaves, then try to turn each handle. Nothing should move. Lift the bar straight off whenever you want to open the doors.

Fits interior lever handles and knobs on a pair of hinged doors, swinging in or out. If one leaf has no interior handle, or the two sit at clearly different heights, there is nothing for the hooks to hold and this is not the right lock for those doors.
Where it belongs

The back wall of the house

French doors are usually the back of the house: the patio, the deck, the garden side that nobody on the street can see. That is the side worth covering, and it is the side most people leave on factory hardware. This bar goes on at night and comes off in the morning, and it lives in a drawer the rest of the time, so it travels to a vacation rental with a pair of patio doors just as easily. Put a vibration alarm on the glass beside it and the whole opening is covered: the doors cannot be forced, and the pane cannot be worked on quietly.

Layer your defense

The bar holds the doors. The alarm covers the glass.

A pair of French doors is mostly glass, and no bar can do anything about a pane. The TremShield Alarm sticks straight to it and fires 125dB the moment someone pries or knocks on the glass, before they are through it. A back wall usually has more panes than one worth covering, which is why the 6-pack lands at $16.50 an alarm instead of $29.99.

Good to know

Questions, answered calmly

This French door lock bar is adjustable: a pin moves along a row of slots to set the width between the two hooked ends. What matters more than the width is that both leaves carry an interior lever handle or knob, sitting at roughly the same height, so each hook has something to sit on. Stand inside and look at the pair before you order. US shipping is free and returns are open for 30 days if the handles turn out wrong.
Yes. This French door lock bar holds handle to handle, so it works on outward-swinging French doors, which is where a floor brace or a track bar can do nothing at all. It hooks over both interior handles and pins them at a fixed width, so the two leaves hold each other shut and the direction they swing stops mattering.
No. The French door lock bar hooks over the two interior handles and holds itself there. Nothing is drilled or screwed into the doors or the frame, which makes it a clean option for renters and for anyone who does not want hardware in a glass door. It lifts straight off in seconds when you want to open the doors.
No. A French door lock bar like this one works from inside only, so you set it while you are home and lift it off on your way out. It is a lock for nights and for the hours you are in the house, not for an empty house. For an empty house, a vibration alarm on the glass is the layer that keeps working while you are gone.
No. A French door lock bar holds the two handles, not the pane, so it stops the doors being levered or pulled open and does nothing about the glass itself. French doors are mostly glass, and that gap is the one an alarm covers. A TremShield Alarm sticks to the pane and fires 125dB at the first pry or knock, so the quiet way in stops being quiet.
