The Patlock Instant French Door and Conservatory Lock is reliable and long-lasting. This strong build might help slow would-be burglars down. It also uses an easy-fitting system so that you can attach to your handles and secure it in seconds.
 
Along with the lock, you get two tamper-proof spindles that are also quick and easy to install. These add an extra layer of security.
 
The lock is designed in a standard white colour that may better blend in with your interior room. It’s still large enough that it has instant visibility from the outside. So anyone considering breaking in knows immediately that your door has protection.
 
No keys or any type of code is needed with this. Instead, you squeeze to unlock it from the inside. This may need a good deal of pressure to unlock though, so those of you with any sort of weakness in your hands may have to practice.

  • Easy to fit on the handles

Tough Patio French Door Lock 'Box Section'


Tough Patio French Door Lock 'Box Section'
Our Rating:
4/5

The Tough Patio French Door Lock is like a sliding door security bar in a sense. It’s straightforward and unobtrusive, slipping easily across your handles. The design is sleek as well so that it doesn’t stick out that much.
 
Yet, when it comes to looking from the outside, there’s no denying that you have a strong lock attached to your door.
 
This lock also features a solid build that’s rather heavy, but that may give evidence to its sturdy construction. It’s made from 3 mm steel that isn’t easily bent or broken. Even the white powder-coated finish is durable, withstanding scratches so it isn’t prone to chipping.
 
The lock does feature a key design rather than a press and go. It includes a padlock and two keys. Yet, the padlock doesn’t seem as high in quality as the rest of the lock, so it may need replacing.

PROS

  • Unobtrusive and sleek design
  • Easy to fit
  • Solid, heavy construction

CONS

  • Padlock seems lower in quality

For locking and unlocking, slide it in and out of place. Do take some caution when you use it though as there is a chance that this security bar can scratch up your door handles.

Our Rating:
4/5

The Tough & Easy French Patio Door Lock is for two horizontal door handles only. More specifically, it fits P, D, and standard handles.

FAQ and Buying Guide

French doors may be pretty to look at, but they’re not unbreakable for intruders. You can take steps to make them safer, yet. This ranges from ensuring the glass installed is reliable, checking that the hinges can have access from inside the house. Also that you have an extra lock in place.

These security measures aren’t designed the same though, and they should measure up to certain factors of quality. This way, you might have an easier time deciding on which one is worth purchasing.

Type of Lock

Locks for your patio French door come in a couple of styles. Some need you to push and click, requiring no keys or any type of code input to unlock and remove it.

Others resemble more of a lock bar and feature a hook where you place a padlock that opens with an included key.

What works best for your door may be more of a personal preference as both of those types can do the job well.

Visibility

Sometimes, potential intruders need a visible deterrent to make them second guess themselves. When it comes to a French door security bar, they’re usually large enough to be seen from the outside. This may be an ideal way to alert burglars that your home may not be worth trying to break into.

Durable Construction

When it comes to your extra door security, you want it to actually withstand frequent use and tampering. Consider locks made from high-quality plastics and metals as well as tamper-resistant spindles. These types of spindles can’t be removed from the outside once you fit them on.

Also consider locks that have a powder-coated finish. This can help with the aesthetic of the lock because you’ll be looking at it more than intruders. So it’s important the finish can hold up over time without chipping or otherwise wearing down.

Ease of Use

Who wants to struggle attaching a lock on a French door? Although these types of doors may seem difficult to work with, there are locks that you can fit with relative ease. In fact, you might be able to slip the lock on in mere seconds, without using any tools.
