The Knob Small (part 196510) is a genuine Holdfast replacement knob in the small size. Hand knobs are what make a rack adjustable without tools: they let you loosen a fitting, slide or reposition a component, and lock it again at the roadside without carrying a spanner.

The Part Most Likely to Go Missing
Knobs disappear. They get backed all the way off and set down on a bumper during a fitting job, they vibrate loose on corrugation when they were not quite tight, and they get cross-threaded and abandoned. The failure that catches people out is subtler though: a knob that has been over-tightened for years develops a spun or stripped insert, so it turns freely without ever clamping. It looks perfectly serviceable sitting on the rack and holds nothing at all.
Small or Large
Holdfast supplies this knob in two sizes. This is the small one; there is also a large knob (196500). Take the old knob off and compare it against the listing rather than judging from a photograph, and check the thread on your fitting before ordering. If the thread in the fitting itself is damaged rather than the knob, browse the Holdfast spares range for the clamping hardware instead.
Genuine Holdfast Spares
Holdfast has manufactured roof racks and outdoor carrying gear in South Africa since the 1980s, and we keep the individual components available so a single worn part never means replacing a whole rack. Browse the full Holdfast spares range for replacement hardware, or the roof rack range and accessories range for complete kits.
