SFIC stands for Small Format Interchangeable Core. These cores are best for Medium to large scale industrial use.
Single Deadbolt vs. Double Deadbolt- The Single Deadbolt is equipped with a thumb turn on one side of the door, while the other has a key turn. The Double Deadbolt has a key turn on both sides of the door. Double Deadbolt Shown below on the left and a Single Deadbolt on the right.
ANSI- ANSI is a voluntary standard grading system that is used within the door hardware industry to determine the durability and level of security provided by the lock.
Grade 1- Lockset most commonly used in high traffic commercial building doors.
Grade 2- Lockset most commonly used in low traffic commercial building doors
Classroom- The latch-bolt is retracted by the grip on either side of the door, unless the outside grip is locked by either the inside key or the outside key. Operating the inside grip will always retract the latch-bolt.
Passage- Rotating door handles, neither of which lock.
Privacy- Lockable on one side commonly by push-button, emergency release on opposite side.
Storeroom- Always locked on outside requiring key for entry with rotating door handle on the inside which never locks for safe exit.
What is the purpose of a CUSH door closer arm? CUSH is a shortened term for Cush-N-Stop, and it’s used in conjunction with LCN closers. You may also see it abbreviated as “CNS” (Other closer manufacturers offer the same feature but use different terminology to describe it). The CUSH arm has a door stop built into it, so when the arm reaches a certain point in the opening cycle of the door, the arm hits the stop on the shoe and stops the door.
An interchangeable core is a compact keying mechanism in a specific figure-eight shape. Interchangeable cores can be extracted from one lock type (mortise lock, bored cylindrical lock, padlock and so forth) and then installed into another without requiring the removal or disassembly of any single component. These units are readily adapted for master keying systems and can be set up with spare cores and keys for quick replacement when security is compromised.
A butt hinge can found on virtually any residential door and most commercial doors as well. The two leaves of the hinge are connected together with a pin. Hinges are actually quite important and can go a long way in either increasing or decreasing both the security and longevity of your doors.
Spring hinges are the perfect alternative to hydraulic arms and other door closing devices. They are low profile, easy to mount and are available in a variety of sizes and strengths. Spring loaded hinges can be adjusted to fit just about any gate, door or hatch to allow for easy and reliable closing.
A door closer is a mechanical device that closes a door, typically after someone opens it. Choosing a door closer requires the consideration of a variety of criteria including the closer's performance in fire situations, control over the rate of closing, safety, durability, risk of vandalism, anti-ligature and aesthetics.
A depository safe is recommended for businesses that requires a non-returnable deposit such as armored car companies, convenience stores, restaurants, etc.
A Grab bars is a safety device made to enable a person to maintain balance, lessen fatigue while standing, hold some of their weight while maneuvering, or have something to grab onto in case of a slip or fall. A caregiver may use a grab bar to assist with transferring a patient from one place to another. A worker may use a grab bar to hold onto as he or she climbs, or in case of a fall.
A deadbolt is cylinder operated, it may be either a single cylinder or double cylinder. A single cylinder deadbolt will accept a key on one side of the lock, but is operated by a twist knob on the other side. Double cylinder locks will accept a key on both sides and therefore do not require (and often do not have) any twist knob.
Mortise cylinders are threaded, and have a cam on the back
A Mortise Lock is a lock that requires a pocket, to be cut into the door in which the lock is to be fit. Mortise locks are found on older buildings, but they have recently become more common in commercial and up-market residential construction.
An exit device mounted on the egress side of the door can be mounted for rim, mortise, surface vertical, or concealed vertical applications. Touch bar exit devices feature an enclosed mechanism case with a push bar area to allow egress.
Rim cylinders attach with screws and have a tailpiece on the back.
A Sex Bolt is a fastener combining a nut with a screw. The sex bolt consists of a female internally threaded barrel (nut) and a male externally threaded (screw). Both the barrel and screw have heads designed to clamp material between the head of the barrel and the head of the screw, or to bridge the gap between two parts.
An SFIC Cylinder Housing have two fingers that go about halfway down the cylinder that engage the core's plug and are linked with a locking mechanism. SFIC housings are also manufactured for rim cylinders, key-in-knob locks, padlocks, cabinet locks, electrical switches, etc.
