15 Reasons To Not Ignore Hook Lock Latch
Types of Door Latches

Latches are made from a variety of materials as well as finishes and thicknesses according to the requirements of engineering. Engineers can select a galvanized lock to prevent corrosion and to ensure its durability in harsh environments.

Other specifications include the security level required for a particular application. For instance hook lock latches is more secure than a hasp lock and may require the use of a padlock.

Hook and Eye Latch

The hook and eye latch is an easy-to-install method to secure gates windows, doors cabinets, and sheds. It's also great for securing screens, porches and storm panels. No fancy tools are required and hooks can be screwed in manually in a matter of minutes. The screw points are sharp and can be sunk into wood quickly and easily for added stability and security.

To determine the proper hook size, first determine the hook type. Crosby Group (c): Look near the clevis or eye for the embossed hook type and size. The size in inches is on one side, and the size in millimeters is on the other. The clevis grabber hook has an clevis that can be attached directly to chain, while the eye rigging comes with an eye that is large and angled to use with synthetics or wire rope. Pewag(c) Hook type, the size in millimeters and the grade of alloy is embossed on the lower portion of the hook bowl. CMCO Columbus McKinnon(c): Look for "HA 800" or HA 800-1000" and the hook's size embossed on the lower part of the bowl near the clevis.

Laclede(c) is the brand that markets the Cartec chainhook. It is easy to recognize because it features "Cartec" embossed at the bottom of the bowl and safety orange or red. Gunnebo(c) and CMCO Columbus McKinnon both have their names embossed on the lower section of the hook bowl. Gunnebo also has the swivel hook, which is identified by a "ELD" halfway up the bowl. The hook has a large eye that is able to distribute web and round slings.

Clevis Latch

A clevis latch enables users to secure the hook of a clevis to an anchor point and it also helps prevent the hook from slipping loose during loading transfer. Clevis latches are available in a variety of designs, including ones that have spring-loaded handles and those with a safety lock. The safety lock is a great option for slip hooks because it guarantees that the load will not fall off unless force is applied downwards. This feature makes slip hooks for clevis compatible with ASME B30.9 Slings standards and OSHA regulations.

A typical clevis latch has an clevis pin and tang at one end, and a formed head on the other. These clevises are usually made of steel to provide the latch with strength they are usually coated with zinc, silver, or chromium. They're often plated with silver, zinc, or chromium to resist corrosion. They can also be hardened.

These latches are utilized in a variety of applications, ranging from connecting chains and rigging equipment to secure cargo in pickup trucks and on trailers. They are also utilized for heavy duty applications, such as the securement of cranes and machinery.

Certain clevises are molded with folded pieces while others are made from machined pieces. They are built with a base that has a hole, either threaded or not. They can be attached to other parts using the bolt for clevis.

The clevis pin is threaded to fit into an open or slotted hole. The pin is bigger than a bolt and designed to withstand heavy shearing forces as well as an axial load.

A lot of clevis latches are made to withstand the strain and vibrations of use in harsh environments. Some are even certified for overhead lifting, which means they can withstand a greater amount of weight than non-hardened versions. In addition to this, a hardened latch can be plated with a variety metals like nickel, silver, and chromium, to increase its resistance to corrosion. Painting or powder coating can be used to improve their appearance and give them the color.

Self-closing Latch

The latch's locking mechanisms can be as simple or complicated as the overall design. Often, these devices are made of metals for strength and durability. Powder-coated or painted latches can also enhance their appearance. Latches, regardless of the materials they are made of are required to resist bending, shearing and impact forces. The thickness of the barrels, backing plates, and cams are key factors in determining whether they are light-, medium-, or heavy-duty.

It is important to select the latch depending on your security requirements as well as the kind of door or enclosure that you intend to attach it to. A gate for the garden that is lightweight could, for instance, be secured using hook latch. However, a strong shed requires the combination of a padlock and a hasp.


It doesn't matter whether you use an automatic latch or not. The most important thing is that it is properly closed. This will reduce the chance of accidental disengagement, which could cause workplace accidents. If you're unsure how to tell if a self-locking hook is ready to load Look for a lock that has an internal stop mechanism or trigger mechanism that blocks it from opening.

Another important consideration is handedness. Certain designs of bolt, rotary, and slam latches are designed to be left-handed or right-handed. Left-handed latches are usually positioned in the middle of the latch on doors that face inwards toward the interior. The right-handed models are put on the outside of the doors and are used for doors that face away from the inside.

There are also special latches that can be used to bypass the Adams Rite-style commercial door locking latches on a lot of bus and truck fleets. These tools enter the assembly through a cutout in the door's side close to the latch. They then pull on the swing bar to pull the latch back. These tools are available online 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 a variety of latches. Each has a specific function. Common latches for doors include hook cam, clevis and hook latches, compression latches, and rotary ones. Some latches include locking mechanisms, such as keys for locks or a panic bar. Latches can be made of various materials, with the metals being the most well-known. They may also undergo additional processes to improve their surface qualities. The most common finishes for latches are polishing, plating, powder coating, and painting.

A keyed latch is the form of a cylinder, and requires a key to unlock. Cylinders have pins and tumblers that align with the cuts in a key to unlock the latch. Certain locks come with additional features, such as anti-pick or anti-drill protection.

Another type of latch is the hasp consisting of a steel strap and a staple. The staple is attached using hinges to the other end of a strap that has slots inside it. Other materials like plastic and rubber can be used to create latches, however, metals are preferred due to their shapeability, machinability, and durability.

Door latches are usually made from metals, however there are exceptions. Certain latches, like are made from plastic to help reduce weight or to meet other design specifications. Other latches have specialized uses like latches designed to be activated with the lever or handle. This permits emergency exits from buildings and other areas.

There are two types of door latches, including levers and knobs. Knobs are typically found on older doors while levers are more popular in the latest designs. look at this website are reversible, meaning that they can be opened from either side, which is especially suitable for doors in interiors where there are no windows. A"pawl lock" is a straightforward version of a cam-lock which can be unlocked by reverse the quarter-turn. It's commonly used in electronic enclosures trailers, buses, trucks, and RVs.
