FITS LEFT HAND HINGE ONLY.  We also sell a handed pair that can be fitted to both hinges (see our other items)

See additional Photos for fitting instructions

• Not suitable for modern styles that do not have the long rod behind the flap
  
• Fits rods up to a maximum diameter of 5.5mm
• We also sell a heavy duty letter plate spring, suitable for larger letter plates (see our other items)

Pack of 2 letterbox springs. These springs are suitable for most traditional style letterboxes (eg. Victorian style). If your letterbox uses this type of spring you should be able to see the spring behind the flap. The spring slides over a long rod as shown in the additional photographs. This type of letterbox is still manufactured, but there are also many modern styles which take much smaller springs. Some modern styles of letterbox are not easy to disassemble and (as far as we are aware) replacement springs are not available for them. 

The springs in this listing have an internal diameter suitable for rods up to 5.5mm diameter but work equally well with smaller diameter rods. The springs are made from 1.4mm diameter galvanised wire for corrosion resistance. This is a slightly thicker gauge of wire than that used in some of our other letterbox springs and as such gives a good restoring force for the length of the coil (a firm feel and should resist most winds). 

Full dimensions are shown in the additional photographs along with a series of pictures showing how the spring is fitted. Please note that this spring will only fit the the left hand hinge of the letter plate as shown in the additional photographs.
