A carabiner or karabiner, often shortened to biner or to crab, colloquially known as a (climbing) clip, is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word comes from the German Karabiner, short for Karabinerhaken, meaning "carbine rifle hook" used by a carbine rifleman, or carabinier, to attach his carbine to a belt or bandolier.
Handcuffs are restraint devices designed to secure an individual's wrists in proximity to each other. They comprise two parts, linked together by a chain, a hinge, or rigid bar. Each cuff has a rotating arm which engages with a ratchet that prevents it from being opened once closed around a person's wrist. Without the key, the handcuffs cannot be removed without specialist knowledge, and the handcuffed person cannot move their wrists more than a few centimetres or inches apart, making many tasks difficult or impossible.
A shackle, also known as a gyve, is a U-shaped piece of metal secured with a clevis pin or bolt across the opening, or a hinged metal loop secured with a quick-release locking pin mechanism. The term also applies to handcuffs and other similarly conceived restraint devices that function in a similar manner. Shackles are the primary connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly. A shackle is also the similarly shaped piece of metal used with a locking mechanism in padlocks. A carabiner is a type of shackle used in mountaineering.
A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams, by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an electronic or mechanical keypad. Types range from inexpensive three-digit luggage locks to high-security safes. Unlike ordinary padlocks, combination locks do not use keys.
A coil spring is a type of spring made out of a long piece of metal that is wound around itself. Coil springs were in use in Roman times, evidence of this can be found in bronze Fibulae — the clasps worn by Roman soldiers among others. These are quite commonly found in Roman archeological digs.
A mousetrap is a specialized type of animal trap designed primarily to catch and, usually, kill mice. Mousetraps are usually set in an indoor location where there is a suspected infestation of rodents. Larger traps are designed to catch other species of animals, such as rats, squirrels, and other small rodents.
A shim is a thin and often tapered or wedged piece of material, used to fill small gaps or spaces between objects. Shims are typically used in order to support, adjust for better fit, or provide a level surface. Shims may also be used as spacers to fill gaps between parts subject to wear.
Padlocks are portable locks usually with a shackle that may be passed through an opening to prevent use, theft, vandalism or harm.
A latch or catch is a type of mechanical fastener that joins two objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a keeper or strike.
A lock bypass is a technique in lockpicking, of defeating a lock through unlatching the underlying locking mechanism without operating the lock at all. It is commonly used on devices such as combination locks, where there is no natural access for a tool to reach the locking mechanism. Because the mechanism itself is not being manipulated, this could technically not be considered lockpicking at all. However, it does fall under the repertoire of techniques used to open locks. Lock bypass is one of the most important parts of locksmithing, especially with respect to public buildings which must be able to be opened from inside in case of fire, thus allowing the use of "letter box tools" among other techniques. Locks may be bypassed by a variety of other techniques including loiding, i.e. the "credit card" technique, against self-closing "latch systems."
Spring steel is a name given to a wide range of steels used in the manufacture of different products, including swords, saw blades, springs and many more. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant deflection or twisting.
A suspension lift is a modification to a vehicle to raise the ride height. It is done for the purpose of improving the off road performance of SUVs or trucks and other off-road vehicles, or for cosmetic purposes. Suspension lifts can enable steeper approach, departure, and breakover angles, higher ground clearance, and helps accommodate larger wheels and tires. Due to the raised center of gravity, maximum safe operating angles can be reduced and roadholding is often significantly impaired. Sensors, transmitters and cameras may need to be recalibrated, physically relocated or modified to maintain normal functioning of features like AEB, ACC or FSD. Suspension lifts are also found on a number of high performance sports cars, in which a very low ground clearance is used to improve handling, using an aerodynamic effect known as downforce; examples include the Ferrari 488, Lamborghini Huracan, McLaren 720S, and the second generation Ford GT. Such vehicles activate the suspension lift while traversing road bumps and ramps to avoid damaging the front underbody of the vehicle when driving on public roads; the suspension lift is deactivated on race tracks and level roads.
Master Lock is an American company that develops padlocks, combination locks, safes, and related security products. Now a subsidiary of Fortune Brands Innovations, Master Lock Company LLC was formed in 1921 by locksmith-inventor Harry E. Soref and is headquartered in Oak Creek, Wisconsin. In 1970 the company was purchased by American Brands from Soref's heirs. American Brands was later renamed to Fortune Brands, which then split on October 3, 2011, to create the Fortune Brands Home & Security company and the beverages company Beam Inc..
Snake shot, rat shot, or dust shot, more formally known as shotshell or canister shot, refers to handgun and rifle cartridges loaded with lead shot canisters instead of bullets, intended for pest control. As the names suggest, the main targets for such ammunition are snakes, rodents, birds, and other pests at very close range.
A motorcycle's suspension serves a dual purpose: contributing to the vehicle's handling and braking, and providing safety and comfort by keeping the vehicle's passengers comfortably isolated from road noise, bumps and vibrations.
Door breaching is a process used by military, police, or emergency services to force open closed or locked doors. A wide range of methods are available depending on the door's opening direction, construction materials, etc., and one or more of these methods may be used in any given situation. In the United States, residential doors typically open inward while commercial building doors usually open outward. Some breaching methods require specialized equipment and can be categorized as one of the following: mechanical breaching, ballistic breaching, hydraulic breaching, explosive breaching, or thermal breaching.
A belly chain is a physical restraint worn by prisoners, consisting of a chain around the waist, to which the prisoner's hands may be chained or cuffed. Sometimes the ankles are also connected by means of longer chains.
Boron steel refers to steel alloyed with a small amount of boron, usually less than 1%. The addition of boron to steel greatly increases the hardenability of the resulting alloy.
A glass breaker is a hand tool designed to break through a window glass in an emergency. It is a common safety device found in vehicles to aid in the emergency extrication of occupants from a vehicle, as well as in some buildings.
A bolt snap is a type of snap hook with a manually operated bolt action slide gate of medium security used to clip a light load to a ring, eye, loop or bight to temporarily secure or suspend an object. They are used for a wide variety of applications including dog leads and for clipping scuba equipment to the diving harness. A similar but more secure device used to attach sails to a stay is known as a piston hank. It differs from a snap shackle in that the load is not carried by the gate. The bolt snap must be actively operated by the user to clip or unclip, and is not easily snagged or unintentionally clipped or unclipped by pressing or bumping against the surroundings.
