Does this case comply with BS3621 please? I already have the cylinder but just want to replace the case. Thanks.
Chris, Stratton
This lock case does not comply with BS3621 unfortunately. In order to achieve a BS3621 rating you could combine an insurance approved cylinder with the Union L2244E - Euro Cylinder Sashcase (67mm).
