These are the requirements from the insurance company.

“If external, it must be used with a padlock

conforming to BS EN 12320 Security Grade 5 (including

amendments) . If the locking bar is internal, it must be used

with a padlock conforming to BS EN 12320 Security Grade 4

(including amendments). The padlock bar must be of similar

strength to the padlock and designed to be used specifically

with the padlock, in both cases the padlock bar must be

secured to the door with coach bolts”.

I have a grade 5 padlock, what locking bar or hasp can I use to fit the 14 mm lock. Can I just buy any solid looking hasp?

Mr Manning, New Zealand

 

This is a good question and the short answer is no, there is not a CEN grade or corresponding grade for a Hasp and Staple. To confuse things further, most of the very secure Hasps are not compatible with the most secure padlocks due to the hole in the staple being too narrow.

So in the case above, Mr Manning has a CEN 5 lock with a 14mm shackle which will not fit Squire’s CEN 5 equivalent Hasp. Therefore the only recommendation we can make at the time is the ABUS 125/150 Hasp which can be used with the lock he already owns.
