Change a Euro Cylinder

Read below on how to remove and measure your UPVC Cylinders

 

Step 1. Locate Cylinder

 

1. Step 1: Locate the euro cylinder fixing screw on the side of the door locking strip. It is the screw that lines up with the bottom of the barrel cylinder. See photo.
    

Step 4. Measure Cylinder

 

1. Step 4:

   Measure from the centre of the fixing screw hole to one end of the cylinder. This is Size A. Then measure from the centre of the fixing screw hole to the other end. This is Size B.

   For example, if one side measures 40mm and the other side measures 60mm, you would order a 40/60 Euro cylinder.

   Important - Euro cylinders are supplied in 5mm increments.

   If your measurement falls between two available 5mm sizes, round UP to the next 5mm size. Never round down.

   Examples:

   33mm → 35mm
   44mm → 45mm
   47mm → 50mm
   52mm → 55mm

   If one side is already an exact 5mm size, leave that measurement unchanged. For example, if your cylinder measures 55mm on one side and 44mm on the other, you would normally order a 55/45 cylinder.

   If your measurements seem unusual or you are unsure that you have measured correctly, measure again from the centre of the fixing screw hole to each end before ordering.

   Thumbturn cylinders: When ordering a thumbturn cylinder, Size A should be the side with the thumbturn. Make sure you know which measured side requires the thumbturn before ordering.

   
    

Before ordering: Check both cylinder measurements carefully. Euro cylinders are supplied in 5mm increments, so measurements that fall between sizes should normally be rounded up to the next 5mm increment and never rounded down.

step 1. Locate Cylinder

 

1. Step 1: Locate the euro cylinder fixing screw on side of the door locking strip, It is the one that lines up with the bottom of the barrel cylinder. see photo.
    

Step 2. Key Position.

 

1. Step 1: Once the euro cylinder screw is fully removed, turn the key to face approximately “10 past” on the clock (see picture) then pull the cylinder out slightly jiggling the key.

   This will allow the euro cylinder to be removed. In some cases some slight turning of the key will help the barrel come out easier, also loosening the bolts on the handles can help the euro cylinder to be removed if it is tight.

    

Step 3. Remove Cylinder

 

1. Step 1: Pull out the cylinder fully and place on suitable surface to measure
    

Step 4. Measure Cylinder

 

1. Step 1: To measure a cylinder you have to measure the distance from the centre screw hole to the outside of the cylinder on one side and then do the same on the other.

   So the barrel in the picture would measure as a 40/60. On the order screen you would order size = 40 , size B = 60.
