Onslow Long Plate Unsprung Door Handle & Thumbturn – Polished NickelOur flat fronted Onslow door knob is a contemporary alternative to our beehive design. This version includes a low profile, long backplate with a built in thumbturn. The knob is unsprung, which means you can use it with an existing sprung latch. To make sure it stays easy to turn, we'd recommend using a lightly sprung latch. Theres also no danger of it coming away in your hand weve engineered the backplate and knob to be inseparable.
