Door Handles. Monday , October 01st , 2018 - 21:37:55 PM
Depictions of door handles in paintings dating to the first century CE are centrally placed hinged rings. The modern door knocker is a vestige of this style of primitive door handle. Doors were typically secured by bars and brackets to prevent them from being opened by either intent or accident. Over time, large crossbars used to secure a door were supplanted by sliding bars, operated by a handle secured to the bar and projecting through a slot in the door, or as a pivoting bar - often called a latch - that could be dropped into a matching slot on the door jamb. In Colonial America, the operating mechanism for a small pivoting bar was a latch string threaded through a hole in the door near the handle. There are - probably apocryphal - accounts and references implying that this mechanism was a workaround for heavy taxes and a crown edict mandating the colonists could only use door latches or locks imported from England. About the middle of the 18th century, handles and locks were integrated into a single unit, the earliest known examples being levers that both operated the latch and served as a pull to open the door.
Security is, of course, your main concern when looking for a door accessory. Latches, locks and handles need to fit perfectly and last long. Some people are eager to splurge on high-tech lock sets like keyless and card-swipe systems. However, you need to be sure if they are 100% reliable. For your front and back doors made of solid materials like wood, a single cylinder dead bolt would do. However, if you have delicate glass doors, which are accessible and attractive to burglars, your better option would be a double cylinder dead bolt, which needs to be opened with a key from both inside and out.
