From The Anvil 102mm (4 Inch) Tubular Deadbolts

4 Inch Bathroom Deadbolts with an 82mm Backset

The From The Anvil 4 inch, or 102mm, heavy duty tubular deadbolt has a backset of about 82mm, measured from the door edge to the centre of the spindle hole. It is a long backset that sets the thumbturn further in from the door edge.

It is thrown by a bathroom thumbturn with a 5mm spindle, and fitted with a separate latch to lock a bathroom, toilet or cloakroom door. Pair it with 4 and 5 inch long backset latches so the thumbturn lines up with the handle. Most are CERTIFIRE approved and fire tested to FD-20/30/60.

102mm (4 Inch) Tubular Deadbolts: Questions

Which size tubular deadbolt do I need?

Match the deadbolt to the latch on the same door so the thumbturn lines up with the handle. If you are replacing one, measure the backset, from the door edge to the centre of the spindle hole, and match it.

What do I need with a tubular deadbolt?

A bathroom thumbturn to work the bolt from both sides of the door, and a separate latch with lever handles to hold the door closed. Every From The Anvil heavy duty tubular deadbolt works with any From The Anvil bathroom thumbturn and its 5mm spindle.
