A cremone bolt is a type of door lock that has been used since the 16th century. This type of locking mechanism can be found in many older buildings because it was one of the only locks available at the time.
The cremone bolt gets its name from the French word for “key,” because in ancient times, this type of lock was only opened with a key, while the word “bolt” comes from the fact that it locks by sliding or moving across something else — much like a door bolt. For this lock to work, you need a key with a hole in it that fits over two pins on either side of the door frame.
You also need a metal rod called an escutcheon pin or spindle that is inserted through holes near the bottom edge of your door into corresponding holes on either side of your door frame to hold everything together.
What is a cremone bolt?
A cremone bolt is a traditional locking mechanism based on a vertical rod. The bolt is manufactured from a steel rod that has been hollowed out and curved to form a cylinder. The two pieces are then attached at their centers with an iron rivet which forms the axis around which the lock rotates.
At one end of each is a handle for manual operation but there is also an operating mechanism on both sides allowing it to be turned from either side without having to move anything aside first. One of these mechanisms allows turning by hand while the other uses a key (a round bar with projecting teeth) inserted into a square or rectangular hole in its headstock/hub whereupon it can turn freely about its axis as if mounted on ball bearings or roller bearings.
Are cremone bolts secure?
A cremone bolt is not a very strong locking device and it cannot be recommended for high levels of security.
However, they do add to the aesthetic value of doors when installed in addition to traditional locks like mortice lock or rim/mortise cylinder deadbolt.
Cremone bolts are available in both manual and electric versions. The electric version has a motor that turns the bolt, while the manual version uses a handle to turn it. They can be used on both interior and exterior doors.
Do cremone bolts lock?
A cremone bolt can be used to lock a door.
When the bolt is in the locked position, it prevents the door from being opened from either side. To unlock the door, you need to use the key or turn the handle to rotate the bolt out of the way.
To bolt the door means to lock it using a cremone bolt. You can also say that you have “bolted the door” when you’ve locked it in this way.
The bolt is in the “locked” position when it’s flush with the door. The bolt can be unlocked by turning a key or pushing/pulling on one of the handles attached to each side.
Where can you use cremone bolts?
Cremone bolts can be used on both interior and exterior doors.
Interior Doors: Cremone bolts are commonly used on interior French doors. They can also be used on other types of interior doors, such as bathroom doors or bedroom doors.
Exterior Doors: Cremone bolts can also be used on exterior doors. They are often used on front entrance doors, but they can also be used on back entrances or side entrances.
You can purchase cremone bolts in both manual and electric versions.
What is cremone handle?
A cremone handle is a type of door handle that has been designed to be used in conjunction with a cremone bolt. A manual version consists of two levers attached to the edge of the door, one on each side.
An electric version uses an electronic keypad and will have no visible handles when the lock is not being operated from either outside or inside.
You can purchase both types at most hardware stores.
Design: Cremone Bolt Cabinet Hardware
A cremone bolt is a type of hardware, often used for cabinets that must remain securely closed and locked in places, such as file cabinets and desk drawers and doors. The bolt is a metal rod or bar that passes through the door or drawer and is secured on each side by a locking mechanism.
The traditional design of the cremone bolt features two cylindrical knobs at either end of the rod, one which screws onto the door or drawer and one which attaches to the frame. When turned in opposite directions, these knobs tighten or loosen the bolt, securing it in place. There are also more modern designs available that do not require knobs but instead use a lever handle on one end and a cam on the other.
Cremone Bolt Installation
- The cremone bolt is a two-part system, with the handle and the shaft.
- The handle is attached to the door and the shaft goes through the doorjamb into the wall.
- When you turn the handle, it rotates the shaft which causes the bolt to move in or out of the jamb.
- This allows you to securely lock or unlock your door without having to use a key.
What is a bolt grade?
A grade is a measure of the quality and strength of a bolt. The stronger the grade, the more difficult it will be to break or cut through it.
There are three grades available:
- Grade-three bolts have a tensile strength of 140 kilograms per square millimeter (KSI). They’re suitable for use with steel security doors that need extra protection from being pried open.
- Grade-five bolts have 175 ksi worth of tensile strength and can support industrial rollup doors as well as solid wood panels with raised decorative grooves on them.
- Grade-seven bolts have 210 ksi worth of tensile strength – almost enough to keep out most thieves – making them ideal for protecting fire exit doors in commercial settings such as hotels, restaurants, and retail stores. They can even be used with wood-paneled interior doors that have grooves on them!
Grade seven cremone bolts are the most secure of all three grades available on the market today.
The grade is important because it determines how difficult it will be to cut through or pick open your bolt lock mechanism. The higher the grade number means more security for you.
What is the difference between a bolt and a screw?
A bolt is a metal rod or bar that passes through the door or drawer and is secured on each side by a locking mechanism. A screw is a metal rod that screws into the door or drawer to secure it in place.
Bolts are stronger than screws and are less likely to break, making them ideal for use in high-traffic areas or places where extra security is needed. Screws are inferior to bolts as they easily brake making them not ideal for homes needing strong locks.
Conclusion
When combined with other security measures, the cremone bolt can be an effective tool for minimizing theft or unwanted entry into your home.
It is important to consider where you will place the bolt and what type of handle you want it to have before choosing one that works best for your needs!
There are manual versions which consist of two levers attached to the edge door on each side; then electric version using keypads without handles when lock operated from outside.
There are many different types of cremone bolts to choose from, so you must do your research before making a purchase. Be sure to consider the grade of the bolt, as well as the size and weight of the door or drawer that you need to secure. With so many options available on the market today, there is sure to be a cremone bolt that fits your needs!
