Thanks Dale :thumb up: Have had experience with the first stop lock the lock itself is made up with little steel barrels ,you know the key kind of looks like a crown (well i think so).Well one of them came loose inside and i could not get the key in .....Que the panic...took a while but eventually got a needle and managed to get it back into place,lock open and straight into the bin.
Thatch am approved one looks good ,will also look into the disc lock...
