Sanitary Threaded-Stud Pull Knobs
Thread these sanitary knobs into holes so you can open doors and drawers in hygienic environments. They’re commonly used on furniture and equipment in pharmaceutical and food-processing facilities. Made of Buna-N rubber, the seal keeps out contaminants and blocks unhygienic metal-to-metal contact. It’s FDA compliant for direct contact with food, and blue for easy spotting and removal if it falls into your line. Knobs have a 316 stainless steel body, so they resist corrosion from frequent washdowns with harsh cleaners. Highly polished, with rounded edges and no horizontal ledges, they leave no room for bacteria to grow.

Sanitary Threaded-Hole Pull Knobs
With a sanitary design, these threaded-hole knobs are often used to open and close doors and drawers on furniture, machines, and other equipment in pharmaceutical and food-processing facilities. They attach like most knobs in your kitchen—push a screw through the back of a hole and thread these knobs onto the front. The seal is blue, so it’s easily seen and removed if it falls into your line. It’s also FDA compliant for direct contact with food. Knobs have a 316 stainless steel body that resists corrosion from frequent washdowns with harsh cleaners. They’re highly polished with rounded edges and no horizontal ledges, leaving no room for bacteria to grow.
