Shop Door, Gate, Toggle & Draw Latches on Amazon.com
Latches are mechanical closure devices commonly used to secure doors, gates, and lids that do not use a key. They may be combined with other mechanisms when used for shop doors and gates. Familiar types include cam, draw & tension, compression, hook, push-to-close, and rotary latches. A latch is generally a two-piece mechanism made of metal but is sometimes made of plastic. One piece of the mechanism moves into place to secure the closure and a second fixed piece is where the latch catches. A toggle latch frequently employs a wire and hook and uses a cam action to tighten the closure. This type of closure is commonly seen on tool boxes. Gate and door latches have a variety of configurations and uses. They may allow opening from one or both sides but generally only allow closure from one side. They may be used in a variety of environments and have varying load requirements. A stainless steel door or gate latch resists corrosion and can be used in harsh environments. A heavy duty mechanism can be used to secure a lid subject to stress or vibration. One closure includes a support rod and is frequently seen with heavier box lids. Other types use a rotating hook to engage the catch. Some incorporate a security hasp to use with a padlock.
