Frequently asked questions
An 8mm spindle is included as standard — suitable for most UK internal doors up to 45mm thick. Longer spindles are available separately for thicker or rebated doors.
Yes — pair it with a bathroom mortice lock or a turn-and-release set for privacy on bathroom and WC doors.
Many of our handles are CE-marked and fire-door compatible (FD30 / FD60). Check the specification table above for this product’s fire rating.
Every set is supplied complete with matching fixing screws and full fitting instructions.
A rose is a small round fixing behind the handle; a backplate is a longer plate that can incorporate a keyhole or thumbturn. It’s mostly a style choice.
Customer reviews
Superb quality, feels expensive
The handle feels great in the hand and the matt black is a proper deep black, not grey. Concealed fixings look really clean on the door.
Perfect for our renovation
Bought these for every internal door in the house. Consistent finish, easy to fit and the spindle was included as described.
Great handle, check your backset
Really happy with the quality. Just make sure you measure your backset first — I needed the 57mm latch not the 44mm.
Next day as promised
Ordered at 2pm, arrived the next morning. Exactly as pictured and great value versus the branded equivalents.
