HOLST Polygon Knob - Black
Our HOLST POLYGON KNOB is the simple, contemporary touch you’ve been looking for to finalise your home. Available in sleek tones — Brass, Matt Black, and Satin Nickel — this sophisticated model brings maturity to cabinets and cupboards anywhere in your home. Its smooth surface finish is contrasted by defined, angular edges that you can get to grips with, feeling hardy in your hands. Style with the PEARCE designs from our premium collection of door handles for an impressive finish.
Each of our brass knobs are covered in a clear lacquer glaze for long-lasting protection, so shop confidently knowing that your picks will stand the test of time on your DIY furniture projects. All knobs are sold individually and come with enough M4 4 x 25mm screws for straightforward install.
25mm / 0.98"
25mm / 0.98"
20mm / 0.79"
M4 / 4mm / 0.16"
Each knob comes with M4 4 x 25mm machine screws and is simple to install. If your furniture or door already has a knob or handle on it, you may be able to unscrew the current one and replace it using the existing screw. If not, you will need to drill a small hole (or holes) in your door or furniture and tighten with a Philips screwdriver.
Solid brass with matt black finish.
Each brass cabinet knob or handle is coated in a protective clear matt glaze to prevent it from oxidising. Clean with warm soapy water and a soft cloth. Avoid abrasive towels, sponges, cleaning sprays, bleach and hand sanitisers.
