Lion Locks Aluminum Sliding Door and Window Lock

This aluminum lock from Lion Locks is a lock that can be used on all sorts of sliding doors and windows, and that includes the glass variety. The important thing to know is that these are sliding rail locks, which means that they are not the kind of lock you put on the door itself, not on the handle or where it would normally lock. 

Instead, these locks go onto the rails of the sliding door, and you would place them on the rail when the door is closed. This helps prevent the door from being forced open from the outside. However, of course, this is not the kind of lock that you can open and close from the outside. 

That said, if you are happy with a lock that just prevents the door from being opened, without the ability to unlock it from the outside, the Lion Locks Aluminum Sliding Door and Window Lock is a very durable, simple-to-install, and effective option. 

Pros

  • Easy installation
  • No tools required
  • Durable
  • 10 pack
  • Very secure

Cons

  • Cannot be unlocked from the outside
  • This is a rail lock – not a door lock

Ideal Security BK110W Patio Door Bar Lock

This is a really neat sliding door lock, and in terms of being able to open and close the door, it’s very similar to the one we just looked at. This is a bar lock, and you install the mounting hardware to the end of the door and the side of the door frame. 

It features an extending bar that is placed behind the door, in between the end of the door and the frame. The bar can fully extend to prevent the door from being opened from the outside, and as far as kids go, it cannot be opened from the inside; it features a special childproof mechanism to prevent kids from opening it. 

Of course, the Ideal Security BK110W Patio Door Bar Lock is a secure way to ensure that sliding doors cannot be opened. However, as with the previous product, remember that this is not a keyed door lock, so if the door is locked from the inside, you will not be able to unlock it from the outside.

Pros

  • Easy to mount
  • Very secure
  • Simplistic design
  • Very durable

Cons

Cannot be opened from the outside

Cal Security Enterprises Double Bolt Lock

The Cal Security Enterprises Double Bolt Lock is yet another sliding glass door lock that works only from the inside. However, this model is different in style and design from the others we have looked at. Unlike the rail and bar locks, this one connects to the door it opens, and to the door frame.

In terms of style, it’s much like a lock for a dog kennel − it features a handle with double bolts that click in and out of the locking mechanism. The Cal Security Enterprises Double Bolt Lock is very easy to install and mount, and it’s easy to open with a single hand. Just make sure to install it high enough so your kids cannot get to it. 

This is another type of lock that does not have a key, so once the door is locked from the inside, it cannot be opened from the outside. 

Pros

  • Easy installation
  • Very easy to use
  • Secure design
  • Great for when the kids are around

Cons

Cannot be opened from the outside

Sliding Glass Door Lock

This final option is very unique compared to the others because the Sliding Glass Door Lock is designed for glass display cases, such as you would find in stores − not for balcony or patio doors. 

This type of lock is ideal for a sliding glass display case, as you don’t have to use any tools or drill holes. Simply slide one end over the end of the door, and that’s it. 

This is a simple way to keep display cases closed, and it’s ideal for keeping both kids and thieves out. The lock itself is made of normal metal, and it’s not like it’s the toughest option out there, but it will be enough to deter thieves.

Conclusion

Which product you choose depends on the type of door you have and the lock you need. The Toledo Fine Locks Sliding Glass Door Lock is our top recommendation because of the heavy-duty spinning steel bolt, and its versatility.
