Sliding Glass Door Security

Aside from the door and window security hardware previously discussed, there are other areas of the home that can be improved with the addition of other types of locking systems. These systems can supplement existing security, or they can also become the main burglar deterrent. Many of these systems are designed for security outside the house, in areas such as garages, sheds, and even for vehicle security. The options are always growing.

Choosing Locks and Chains

Numerous padlocks and chains are available for use in home security. The security rating of a padlock is generally related to its size and cost, and the same can be said for chains, which are generally used for looping through gates or securing movable items like ladders or motorcycles. The best use of each item is usually specified by the manufacturer.

Hasp lock: A hasp lock provides a reliable way of padlocking a door (see below). Attach to frame

Pad bolt: This is much the same as a standard door bolt, except that it can be secured using a padlock. Note: Attach to frame; Attach to door.

Open-shackle padlock: Traditional padlock shape with the shackle in the form of an elongated loop.

U-lock: This U-shaped frame is ideal for locking bicycles.

Security chain: Steel chains are commonly used for padlocking bicycles, motorcycles and gates. Note: vinyl covering

Locking cable: This hardened steel cable is perfect for locking down large items such as lawnmowers and motorcycles.

Keyless Locks


The disadvantage of any key-operated system is that the key can be lost. Combination locks are an alternative. They open when you enter the right number. With a combination padlock, you can change the combination number to one you will remember.

Securing Out-Buildings

Garages and sheds are particularly vulnerable to burglary and should always be well secured; not only do they contain valuable items, but some items can be used by burglars to gain access to the main house. Ladders are the most obvious aid, but any number of garden tools can be used to force entry. Most of the systems shown on the left are ideal for use in garages and sheds. Looks aren't important with these items. Choose those that achieve the greatest level of security.

Installing a Hasp Lock

Padlock security is commonly used on outbuildings because the doors often do not have the thickness to accommodate cylinder locks or mortise locks. Where door design does allow, padlocks are often used as a second line of defense. The best way of using a padlock is by hanging it through a hasp mechanism. When installing the latter, the plate of the hasp must be installed so that it hides the screws when locked. When choosing a padlock, be sure that it's suitable for outdoor use; “all-weather use” is a common manufacturer’s specification. In the sequence below, a combination padlock is used. The main alternative to a hasp lock is a pad bolt with a padlock.

A. Mark the screw holes for the hasp. Make pilot holes for the screws.

B. Screw the hasp to the door.

C. Mark the screw holes for the staple. Make pilot holes for the screws, then screw the staple to the door.

D. Secure the hasp lock with a padlock.
