Description
- The Union Architectural range features a cleverly designed double spring mechanism – the first spring powers the spring bolt when the door is closed
- The second spring only applies its force to the spindle and consequently the door furniture
- 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
- Backset to keyway 38mm
- Backset to follower 101.5mm
- NOTE: Intumescent should be used to ensure adherence to fire regulations
