At Locks4, we supply a broad range of cylinder locks, each individually suited to any home. More commonly known as a pin tumbler, a cylinder lock’s mechanism functions with several internal pins that move within the inside of the cylinder as the key is tuned thanks to the serrated edges.
The pin tumbler mechanism originated first with a primitive lock designed by the Egyptians about the time of the pharaohs. It wasn’t developed again until Linus Yale invented his pin tumbler lock which were originally supplied for bank and safe locks.
Current cylinder locks come in all shaped and sizes from a standard yale type rim cylinder on your wooden front door, cam locks, padlocks, screw in cylinders and the most popular by far is the euro profile cylinder which is found in almost every UPVC and aluminium door ( old aluminium doors not using a multipoint mechanism have an oval cylinder. )
Most cylinders are available in various finishes:
N or NM = Nickel / Nickel Matt
PB or B = Brass or Polished Brass
CH = Chrome
There is a large amount of different manufacturers almost all of them making a full range of every type of cylinder and as with most things there are good quality products and poor.
We carry extensive stocks of all sizes of cylinders complying with BS3621 / BS EN TS 0007 3* ensuring that the lock you order will meet you insurance requirements.
When reviewing the practical side of cylinders, the simple ability to remove the cylinder and replace it with a new one, with the reassurance that you don’t need to remove and replace the entire lock system.
