How it works?
Letterbox Sentry is installed on the rear of any standard letterbox and can be set to lock and unlock at predetermined times.

– Reduce theft of keys through the letterbox
– Reduce junk mail
– Simple and easy DIY fit
– Peace of mind.

Stops Burglary
The letterbox sentry™ “TG1” & “FG1” prevents burglars from gaining access through the letterbox using a unique and automated design thus preventing “key fishing”

Perfect for combating arson attacks on properties, the FG1™ will stop fireworks and accelerants being posted,
Automatically locking the letterbox should it detect any accelerant and setting off the inbuilt alarm.

Eliminates Junk Mail
Set the letterbox sentry™ to lock and unlock at desired times before the postman is due and early evening when no post is expected to eliminate all junk mail and unwanted objects from being posted in to your property…
