Why Choose This Lock?
A 5-lever mortice lock is widely recommended by South African insurance companies as a minimum security requirement for external doors. The BBL Sash Mortice Lock exceeds basic requirements with triple anti-tamper protection — drill, saw, and pick resistance — giving you confidence that your property is protected against the most common forced-entry methods.
The sash-style mechanism allows the door to be locked and unlocked from both sides with a key, making it well-suited for doors that require secure, controlled access.
Frequently Asked Questions
What is a 5 lever mortice lock?
A 5 lever mortice lock is a high-security lock that fits into a recess (mortice) cut into the door edge. It uses five levers internally, which must all align correctly for the bolt to operate. South African insurance companies typically require a minimum of 5 levers for external door locks to qualify for cover.
What is a sash mortice lock?
A sash mortice lock is a type of mortice lock that is keyed on both sides — there is no handle or knob. Both the inside and outside of the door are operated with a key. This makes it ideal for doors that require controlled, key-only access from both sides, such as security gates, outbuildings, and perimeter doors.
What backset does this lock use?
Please check the product specifications or contact us to confirm the backset before ordering. The backset is the distance from the edge of the door to the centre of the keyhole, and it must match your door preparation.
Is this lock insurance-compliant?
Yes. A 5-lever mortice lock is the standard minimum requirement specified by most South African insurance companies for external wooden doors. The anti-drill, anti-saw, and anti-pick features of this lock exceed the basic requirement.
Can this lock be keyed alike with other locks?
Keyed alike options may be available — contact us before ordering if you need multiple locks to operate on the same key.
Does this lock come with a strike box?
