Hand knobs, inserts, handles
Tulplast is a manufacturer of hand knobs, feet, threaded inserts and handles. Owing to precise production, our adjusters are top-quality components made of plastic and metal. Our extensive offering includes threaded inserts and inserts with metal thread. Threaded plugs are available in black. Inserts can also come in grey. Threaded inserts are made of a very strong plastic to make the thread inside the plug resistant to impacts.
What distinguishes us from the competition is the state-of-the-art method we use to manufacture our adjusters. When a machine bolt or nut is moulded over, the produced star knobs and adjusting feet never become loose at the in-moulded thread, making them very durable and resistant to environmental conditions. Our knob offering also includes self-assembly knobs and wingnut knobs with their characteristic light and durable design. We have expanded our offering of threaded inserts, feet, knobs and plastic handles with threaded sleeves and through holes with handles for boiler doors.
