Link Round Stainless Steel Knob Lock

A Link Round Stainless Steel Knob Lock is a type of door lock that is commonly found in residential and commercial buildings. It is named for the cylindrical knob on the door's interior, which is turned to lock or unlock the door. Knob locks are often used in conjunction with deadbolts for added security. Here are some key features and characteristics of knob locks:

1. Design: Knob locks consist of a knob on the interior side of the door and a keyed cylinder on the exterior side. The knob is attached to a spindle mechanism that extends through the door to the cylinder, allowing the knob to be turned to operate the lock. Some knob locks have a push-button or twist-button mechanism on the interior side for locking and unlocking without a key.

2. Keyed Entry: Knob locks are typically operated with a key from the exterior side of the door. The keyed cylinder contains a series of pins or tumblers that align when the correct key is inserted, allowing the lock to be turned and the door to be unlocked. Some knob locks may have a keyhole on both sides of the door for added convenience and security.

3. Latch Mechanism: Knob locks use a latch mechanism to secure the door when locked. The latch extends from the edge of the door into the door frame, preventing the door from being opened from the outside. The latch is retracted when the knob is turned or the button is pressed, allowing the door to be opened freely.

4. Security: While knob locks provide a basic level of security, they are generally considered less secure than deadbolts. This is because the cylindrical design of the knob can make it vulnerable to forced entry methods such as wrenching or prying. For this reason, knob locks are often used in conjunction with deadbolts to provide additional protection against intruders.

5. Installation: Knob locks are relatively easy to install and can be retrofitted to most standard doors. They are available in a variety of finishes and styles to match the aesthetics of the door and surrounding hardware.
