When it comes to choosing door handles and locks, the first aspect a buyer is likely to consider is the design and look of the hardware.
But though the range of styles and finishes is practically endless, the actual number of basic models is fairly limited, and these must meet certain standards, which makes the choice somewhat easier.
In addition to style and look, there are other important aspects to take into consideration, such as ergonomics, ease of installation, quality and, of course, security.
Does the door open to the right or to the left?
Is the new hardware for the front door or for an interior door?
Do any users have reduced grip or restricted hand movement?
Is the new hardware a replacement or is it to be fitted on a brand new door?
Cylinder and guard
The cylinder contains the lock mechanism. It is protected by strong metal shield, the cylinder guard, which fastens to the cylinder collar. Inserting and turning the key actuates the deadbolt. The cylinder is located on the outside of the door. Some lock manufacturers make systems that can be configured so the user can activate or deactivate the keys that can be used with the lock, without having to call a locksmith.
Solid metal cylindrical bar with a flat end, which locks the door by being projected into the strike. The bolt is actuated by the key or thumbturn.
Thumbturn (or turnbutton)
Button that actuates the bolt from the inside, to lock or unlock the door.
Metal plate with an opening, fastened over the hole in the door frame, which receives the bolt that closes and/or locks the door.
Decorative plate surrounding the door handle.
Metal rod that links the two parts of the doorknob and actuates the lock when turned.
Metal plate with an opening, fastened over the hole in the door edge, through which the bolt moves.
Solid metal cylindrical bar with a bevelled end, which holds the door closed when projected into the strike. The bolt is spring-loaded and actuated by the doorknob or lever. When the door is opened, the bolt retracts. When the door closes, the bevelled end of the bolt slides past the rounded edge of the strike plate and engages in the strike hole.
Door hardware comes in a variety of finishes, the most common being brass, polished brass, antique brass, pewter, stainless steel, satin nickel and satin chrome.
The size and rounded shape of the doorknob are designed to fit in the palm of the hand.
Exists in "passage", "privacy" and "keyed" versions.
This type of handle is simple for people of all ages to use, which explains why it is becoming an increasingly popular choice.
In the past, this mechanism lifted a latch in the form of a horizontal metal bar. The modern version operates a bolt.
A standard colour code, usually shown on the product packaging, indicates the type and function of the door handle (knob or lever) or lock. No code is used for thumb-latch (entrance) locksets, traditional bolts or electronic locks.

A variation on the night latch, this lock consists of a vertical cylinder that locks into rings attached to the door frame.
When choosing door hardware, especially for the front door which is used most often, do not compromise on quality. Purchasing a high-quality product will provide security, reliability, durability and ease of use, as well as minimum maintenance.
As handles and locks are used countless times during their life, they may occasionally need to be re-tightened or lubricated. Only use lubricants formulated specifically for door hardware. Conventional lubricants could damage the mechanisms.
