Types of Door Latches
Latches can be made in a variety of materials in various thicknesses, finishes, and finishes to meet specific engineering specifications. Engineers can pick an electro-galvanized lock to avoid corrosion and ensure long-lasting durability in harsh environments.
Other specifications include the level of security required to secure an application. For instance, a hook lock latch is more secure than a hasp and could require the use of padlocks.
Hook and Eye Latch
The hook and eye latch is an easy-to-install method to secure gates doors, windows cabinets and sheds. It's also great for securing porches, screens and storm panels. The hook can be screwed into place by hand without the use of any fancy tools. The sharp screw points bite into wood easily and efficiently to provide extra security and stability.
To determine cabin hook lock of the hook, you must first determine the type of hook. Crosby Group (c): Check the eye or the clevis for the embossed hook type and size. The size is shown on both sides. The clevis grab hook has an clevis that can be used for direct attachment to chains, whereas the eye rigging hook has an eye that is large enough for use with synthetic rope or wire rope. Pewag(c): The hook type, size in millimeters and the grade of alloy is embossed on the lower portion of the hook bowl. CMCO Columbus McKinnon (c): Look at the "HA 800" or "HA 800-1000" and the size of the hook on the lower part of the bowl, near the clevis.
Laclede(c) sells the Cartec chain hook. It is easy to identify by its "Cartec" embossed at the bowl's bottom and safety orange or red. Gunnebo (c) and CMCO Columbus McKinnon have their names embossed on the lower portion of hook bowl. Additionally, visit your url has a swivel hook that's identified by an "ELD" mark mid-way into the bowl of the hook. The hook has a large eye that can spread web and round slings.
Clevis Latch
A clevis latch enables users to secure the hook using clevis to an anchor point, and also prevents the hook from coming loose during the transfer of a load. Clevis latches are available in a variety of designs and styles, including those with spring-loaded handles as well as those that have a safety lock. This latter is perfect for slip hooks since they guarantee that the load doesn't fall off the hook unless an upward force is applied. This feature makes clevis slip hooks compatible with ASME B30.9 Slings standards and OSHA regulations.
A typical clevis latch has the clevis pin as well as tang at one end, and a head that is formed on the other. The clevises are usually constructed of steel, which gives strength for the latch. To prevent corrosion, they're often coated with chrome, zinc, or silver. They can be made harder.
These latches are utilized in a myriad of applications which range from connecting chains and rigging equipment to securing cargo in pickup trucks as well as on trailers. They can also be employed for heavy-duty applications, such as the securement of cranes and machinery.
Certain clevises have been made using folded pieces, while others are made from machined pieces. They have a base with a hole, whether threaded or not. They can be attached to other components with a bolt for clevis.
The clevis pin can be threaded and fit into a slotted or smooth hole. The pin is larger in diameter than a bolt and is designed to handle large shearing stresses and can support an axial load.
Many clevis locks are hardened to stand up to the strain and vibrations of harsh environments. Some are certified for overhead lifting. This means they can support more weight than the non-hardened models. A latch that is made of hardened material can be plated with various metals such as silver or nickel to improve its corrosion resistance. Painting or powder coating can be used to enhance their appearance and add colour.
Self-Closing Lock
The locking mechanisms can be as complicated or simple as the overall design. The majority of these devices are made of metals to ensure strength and durability. Latches that are painted or powder coated can also enhance their appearance. Regardless of the materials used in their manufacture the latches have to be strong enough to withstand bending, shearing and impact forces. The thickness of the latch's barrels, back plates and cams is a crucial aspect when determining if they are medium, light, or heavy-duty.
The type of latch you choose should be based on your security needs and the kind of door or enclosure that it will be attached to. For instance, a light garden gate can be secured using hook latches, while the door to a shed that is strong requires a hasp and padlock combination.
Whether you use a self-closing latch, or not, the most important factor is to ensure that it is shut properly. This reduces the chance of accidental disengagement that could result in workplace accidents. If you're unsure if the hook is ready to be loaded, look for a lock with an internal stop mechanism or trigger.
Another important consideration is the handiness. Certain bolt, rotary and slam designs have been designed specifically for left-handed or right-handed. Left-handed models are usually positioned in the middle of the latch and are used on doors that are facing inward towards the inside of the building. The right-handed designs are located on the outside of the door and are used on doors that open outwards from the interior of the building.
There are also specialized latch tools designed to get around the Adams Rite style commercial door locking latches found on a lot of bus and truck fleets. They are inserted through a cutout on the side of the commercial door that is adjacent to the latch. They extend their reach into the latch to pull an adjustable bar that retracts the latch into the open position. These tools are available on the internet or in the majority of hardware stores that sell Adams Rite latches.
Keyed Latch
Latches are used to keep doors and gates closed. There are numerous kinds of latches and each has a particular purpose. The most common latches for doors include hook cam, clevis and hook latches, compression latches, and rotary ones. Some latches also include locking mechanisms, for example a keyed lock or panic bar. Metals are the most common material for latches but other materials may also be used. They may also undergo additional processes to improve their appearance. The finishes available for latches include painting, powder coating, and polishing.
A keyed latch has a cylinder and requires the use of a key to unlock. Cylinders contain pins and tumblers which align with cuts in a key to unlock the latch. Some locks have extra features, like anti-pick or anti-drill protection.
Another kind of latch is the hasp, consisting of a steel strap and a staple. The staple is attached using hinges to the other end of the strap with an opening in it. Latches can also be made out of other materials, including rubbers and plastics however metals are commonly utilized due to their formability, machinability, and strength.
Door latches are usually made out of metals, however there are exceptions. Some latches, for example, are made of plastic to reduce the weight or to meet other design specifications. Other types of latches are used for specialized applications such as latches designed to be activated by pushing a lever or handle, allowing emergency exits from structures and other areas.
There are two types of door latches: levers and knobs. Levers are more popular on newer designs, while knobs are typically found on older ones. Some latches are able to be opened on either side. This is ideal for doors that are that do not have windows. A pawl latch is a simple type of cam latch that can be locked with one quarter-turn, or unlocked using reverse quarter-turn. It's commonly used in electronic enclosures trailers, buses, trucks, and RVs.
