The most popular of all 4 cylinder lock ranges
Offers value for money
True commercial quality
Features a cleverly designed double spring mechanism; the first spring powers the spring bolt when the door is closed, it is smooth and sufficient for this purpose. The second spring only applies its force to the spindle and consequently the door furniture
This second spring is strong and durable for years of trouble free operation
The big benefit of this second spring action is that it makes the latch well suited to modern round bar furniture, avoiding the droop you see when an economy has been made in the specification of the latch
