Glossary – Door Hardware
28 degree latch:
A latch that requires less rotation on the handle to disengage the latch mechanism. Useful for people with ergonomic concerns, like users who suffer from arthritis.
Bronze:
Bronze is a metal alloy consisting primarily of copper that is commonly used in decorative metal work. It was particularly significant in antiquity, giving its name to the Bronze Age.
Double Deadbolt:
A deadbolt featuring a key way on the exterior as well as a key way on the interior.
Full length Entry Set:
An entry set with a plate that spans the entire length, from the deadbolt to the bottom of the handle grip.
Lost Wax Cast:
An ancient practice in which a bronze sculpture (in our case door hardware) is cast from a wax model. The wax model is dipped in a slurry of silica, then more ceramic material is added creating thick walls around the model. At this point the wax is melted out of the ceramic and you are left with an empty ceramic mould. Molten bronze is then poured into the ceramic mould creating a bronze reproduction of the original wax model.
Passage:
A handle set without an internal locking mechanism. A passage set is used on a door that doesn't require privacy, for example; between a living room and a kitchen or closet.
Privacy Pin:
A pin that engages the privacy feature on the latch from the interior side of the rosette. Can be disengaged in an emergency by inserting a narrow object (like the end of a paperclip) into the emergency release hole on the exterior rosette.
Sectional Entry Set:
An entry set with separate plates for the deadbolt and handle grip.
Strike Plate:
The metal plate installed on the door jamb that receives the latch bolt when the door is closed.
Backset
The backset is the distance from the edge of the door to the center of the 2-1/8" bore hole. In the U.S. there are two common backsets for residential locks, 2-3/8" and 2-3/4". We will pack your locks with a 2-3/8" or 2-3/4" latch depending on which backset you specify.
Deadbolt Latch:
A non-spring loaded locking mechanism that can only be disengaged by rotating the lock cylinder via key or thumb turn.
Dummy Function:
Dummy sets have no latch and are surface mounted so you can install a dummy set wherever you choose on the door, but they are usually located to match the appearance of nearby operating locks. Dummy sets have no latch and are surface mounted so you can install a dummy set wherever you choose on the door, but they are usually located to match the appearance of nearby operating locks.
Handing:
Levers and some handle grips are either Right handed or Left handed depending on the orientation in which the door opens and the side the hinges are located.Read More>>
Monolithic Entry Set:
An entry set with a plate that spans from the top of the deadbolt to the top of the handle grip.
Passage/Privacy Latch:
A spring loaded mechanism that slides it's bolt into a strike plate on a door jamb, securing the door shut and disengages when the attached knob or lever is turned.
Projection:
The furthest distance and object extends off of a surface, like a door or cabinet.
Single Cylinder:
A deadbolt featuring a key way on the exterior and thumb turn on the interior.
Thumb Press:
The flat stub located above the handle on an entry set that disengages the latch bolt.
Bore
A round hole made using a drill, commonly used in reference to tubular door lock preparations.
Door Pull:
A fixed pull attached either directly to a door or with a backplate.
Drive In Latch:
A drive-in latch fits into a 1” round hole on the edge of the door and contains no face plate. It does not require any special preparation or mortising..
Interconnect Device:
The interconnect device provides an emergency egress function on tubular handle sets. When the deadbolt is in the locked position, simply turning the knob or lever will open both latches. It is especially handy in a fire or many other panic situations.
Mortise Lock:
A lockset that fits in a mortised door, featuring a rectangular hole that a mortise lock body slides into.
Patina:
An aesthetically pleasing sheen or coloration that signifies a bronze object's age. Patinas are produced by chemical action, oxidization or sulphuration, during the course of time.

Thumb Turn:
The changing of a lock’s internal pins in order to make the tumbler combination fit a different key.
Wrought Steel:
Steel that is worked to resemble the rustic hand craftsmanship of wrought iron, which is not commonly produced any more.
Brass
An alloy of copper and zinc, brass is the mark of a high quality product in a market where the use of cheaper alloys is becoming more and more common. EMTEK® brass products might look the same as a lesser quality product on the outside, but the finish, strength and lifetime of ours will be superior.
Door Prep:
The dimensions that a door must be bored or mortised in order for a handle set to be installed.
Electronic Locksets:
A lockset using a keypad input and a user code to engage or disengage the latch bolt.
Key In Lockset:
