What is the difference between a heavy sprung and economy tubular latch?

Heavy sprung latches are built with a stronger spring mechanism to support unsprung or heavy handles, ensuring they return to a horizontal position. Economy tubular latches have a lighter spring and are only suitable for sprung handles. Choosing the right latch depends on your handle weight and spring strength.

Can I use a tubular latch on a fire door?

Yes, as long as the tubular latch is fire-rated and tested to BS EN 12209. Always look for CE-marked or Certifire-approved latches for use on FD30 or FD60 fire doors.

Do tubular latches have bolt-through fixing holes?

Some heavy-duty tubular latches include bolt-through holes, allowing secure fixing of door handles through the door and latch body. This provides a much more robust installation, especially for handles on roses or high-use doors.

Q: What backset is best for lever handles or knobs?

For lever handles on backplates, a 2.5-inch (64 mm) backset is ideal. For handles on a rose, use a 3-inch (76 mm) latch to provide enough clearance from the door edge. Mortice knobs should use a minimum 3-inch backset — or longer where the door stile allows — to prevent your knuckles from catching the edge when turning. Always consider door casing depth and style before choosing the correct backset.

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.
