Pack of 2 letter plate / letterbox springs, suitable for rods up to 5.5mm diameter.  The springs are made from 1.4mm diameter wire, giving the letterbox flap a firm feel without making it difficult to hold the flap open whilst posting items through.  The springs will only fit the left hand hinge of the letter plate.  They are intended to be fitted without any modification.

Full dimensions are shown in the extra photograph.  For fitting instructions please read our guide on 'How to fit a letter plate spring'.
