The Best Lock for Sliding Glass Door

Last Updated on September 9, 2024

When your arcadia, sliding glass door lock gets old, it is likely to fail. 

While you could simply replace what you have with the identical item, doing so won’t add additional door security. It is the time to upgrade your sliding door lock and strengthen the security of your door by installing a Double Bolt Lock. 

The best lock for your sliding glass door is a Double Bolt Sliding Door Lock. It is more affordable than replacing the original lock, it is easy to install, it gives you added security by preventing the lifting of the door off its tracks, and it adds child safety.

We recommend this lock to all or our customers that have had an arcadia door lock fail because of the value. The only time you would not be able to use this lock, is when you use the sliding glass door to access the home via a key.

In most cases you can install this lock yourself, but any home locksmith or handyman would be able to assist you if needed.

Benefits of Double Bolt Lock Sliding Door Lock

Prevents the Sliding Door From Being Lifted Out

This sliding door lock prevents the door from being opened by lifting it off its tracks by securing the door from both the top and bottom of the lock. Most of the older arcadia doors can simply be lifted off and opened by a screwdriver. This feature makes this lock the best sliding door security lock available.

Child Protection

It has the added benefit of additional child protection. It requires that both bolts, using two hands, be lifted in order to open the lock, making it difficult for little ones to use.

The newest model also has a small key to lock the bolts in place and can be used, if desired, to completely eliminate the possibility of a little one’s running into the back yard.

Easy to Install

The Lock can be mounted above the existing locks, with just a few screws, so the current sliding door lock does not need to be removed.

We sell the Double Bolt Lock sliding glass door locks for a great price on our website.

• Door cannot be lifted off its track because it secures from both the top and bottom. 
• Child Safety Features.
• Optional adapter to lock two sliding glass doors together.
• Optional handle if needed (or you can use what you already have installed).

Application

We have seen a few patio doors that this lock will not work on. The main issue is with c-channel doors.

C-channel doors have a protrusion in the middle (as opposed to being all flat) that makes it difficult to get the frame side mounting piece installed. To work, you need to be sure you have 1/2″ available to mount the bracket.

If you do not, you will either have to manually cut the bolt locking bracket down to size or go with another option.

Other Sliding Glass Door Lock Solutions

We started installing the Cal Double Bolt Locks when they first arrived on the market about 10 years ago. Up until that time, we were installing Charlie bars for arcadia door security.

Charlie bars are a great step above just a wood dowel in the window track. A wooden dowel prevents the door from being open, but can often be shaken out by shaking the sliding glass door back and forth.

Charlie bars secure to the sliding door with screws, then folded down and locked the sliding door into place via a latch on the frame side, thus the sliding glass door cannot be opened or shaken open.

But, Charlie bars weren’t ideal for securing sliding doors ideal either. While the door was firmly held shut by a Charlie bar, the door could still be lifted out of its tracks with a screw driver and they are pretty ugly.
