Frequently Asked Questions

What backset is best for lever handles or knobs?

For lever handles on backplates, a 2.5-inch (64 mm) backset is usually ideal. If you're fitting lever handles on a rose, go with a 3-inch (76 mm) latch to ensure enough clearance between the handle and door edge. For mortice knobs, a minimum of 3 inches is recommended — or longer if your door thickness allows — to prevent knuckle-banging when turning the knob. Always consider the door stile width and depth of casing before choosing your backset.

Are tubular mortice latches compliant with fire door standards?

Only specific models are. Choose options with BS EN 12209 marking and CE certification—these meet fire safety requirements and regulatory standards.

What’s the advantage of a bolt-through latch?

Bolt-through latches are reinforced with fixing holes to secure handles through the latch case—ideal for high-use or commercial doors needing extra stability.

When should I choose a heavy-sprung tubular latch?

Opt for heavy-sprung models when installing heavy or unsprung handles. Their robust spring ensures handles return correctly and don’t droop over time.
