Steve Neville backplate

A replacement backplate for your Steve Neville alarms, this will fit all Mk.2, Mk.3 heads perfectly, it will also fit the older heads but with the older heads, there will be a small overhang at the bottom and a tiny "whisker" at each side, it will still form a watertight seal still, especially if used with the Steve Neville alarm sealant also available from Dalectronics on eBay.
Any questions please feel free to ask.
These are genunie backs as produced by Steve Neville.
