Maximising Security with Enhanced Door Hardware Features

Understanding Door Hardware Components

There are many components that constitute door hardware such as hinges, locks, jambs, letterboxes, handles and accessories.

The Role of Door Handles in Security

Door handles provide a key role in home and workplace security as they act as a physical barrier that prevents unauthorised access. Strong durable handles offer the below benefits:

• Delay break-ins
• Enhance privacy

Importance of Quality Hinges

Door hinges are one of the weakest points on a door, so it is important to use high quality hinges that can withstand extensive wear and tear. The British Standard for door hinges is BS EN 1935. This standard outlines information on product types, usage classifications, testing cycles, door weights, and corrosion resistance. It also covers definitions, performance requirements, testing equipment, test procedures, and product labelling. Additionally, the published standard includes annexes detailing

The History of Keys

As you read this blog almost certainly you have a small toothed and grooved slab of metal on your person, and you use it every day when entering and leaving your house, lets see how these have changed and developed over the years.

 
Did you know one of the oldest locks on record was created in Egypt? “The ancient Assyrian lock” like our modern method of lock and key which consists of a large wooden pronged key which moved a series of tumblers the design spread globally influenced the future of locks.

The years that followed didn’t see many changes to the operational mechanism of locks however many decorative changes to keys which would have been seen across medieval Europe if your lucky enough you still see keys like this used today.

Jumping forward a few years Robert Barron brought us the lever tumbler lock which offered limited security but a much smoother operation this design was later revised increasing the security.

The late 1700s see the likes Joseph Brahmahs

Unlocking the World: Exploring the Power of Multiple Locks

Locks have been an essential part of human civilization for centuries, providing security and peace of mind. 
While locks are typically associated with a single key opening a single lock, there is a solution where multiple locks can be passed together, allowing multiple locks to work on the same key.

At SDS London, we take pride in our ability to provide this unique service in-house, also allowing us to cut additional keys as requested.

In this blog, we will delve into the concept of passing locks and explore the benefits and possibilities it brings. We will also discuss master keying systems.

 
 
Understanding the Concept of Passing Locks

The concept of passing locks, also known as keyed alike, is based on the idea that multiple locks can be opened by the same key. This allows for more convenient access control, as one key can potentially unlock various doors or compartments.

By aligning the internal workings of different locks,

Why are locks handed?

The term 'handing' related to the direction in which the door travels when it is in use. We need to know about handing in order to ensure the products they supply will be suitable for the doors to which those products will be fitted. Some items of door hardware will only work on doors of a particular 'hand'. Therefore, it is important to ensure the correct handing is supplied.

In particular, we are going to be exploring lock handing. When it comes to handing, some locks are handed. We may ask “Please confirm whether you need this lock to be right or left-handed.” Sometimes it seems ironmongery is made unnecessarily difficult – but we promise this isn’t done on purpose! Some locks are handed because it’s critical to their function, and it is important to ensure the door closes and locks correctly. 

For example, the below lock is a mortice night latch, typically used for apartment doors. The handles are connected by a split spindle, where the inside handle
