Yale Anti-Snap - Euro Thumbturn Cylinder 40 - 40 (80mm) Reviews

A first rate product, as far as I know the only one that can offer the level of security expected by insurance companies. This was a replacement lock for one of the less secure locks that could be removed or broken into quite easily ( see videos on You Tube). This company offer the product at a very competitive price with good service and support. Fitting the lock as a replacement takes only a few minutes and needs only a pozi screwdriver. The thumb turn needs a very small Allen key (supplied) and needs care to ensure you don't drop the screws, as finding them once dropped could present problems

The anti snap lock was spot on for my property, it would have probably prevented a break in
