Cole-Parmer Heavy-Duty Three-Prong Extension Clamp, Dual, Large

Featuring an innovative closed yoke design that minimizes contamination and corrosion of internal components and is easier to clean and decontaminate. This design allows use of the clamp’s full depth – no springs or internal workings to get in the way. Choose single adjustment style for standard use where one prong or “finger” is adjusted using a wing nut, while the other prong remains stationary or for a more versatile clamp choose the dual adjustment style. Utilizing thumbscrews, both prongs are easily adjusted over a wider range. Available in 3 sizes, small, medium, and large. Constructed of nickel plated zinc. Supplied with non-slip vinyl sleeves or for temperatures above 212°F (100°C), fiberglass covers. The prong height for these clamps make them ideal for use in holding and securing glassware with precision ground glass joints.
