This GT3 aka GT2 (3mm) or 3GT Timing belt is made of Neoprene and has Fiberglass Cords for strength. It's great for your automation projects.
The teeth on this belt are more like a rack system. The belt is thicker than standard MXL or GT2 (2mm) and is great for use with Nema 23 size motors where deep tooth engagement is a necessity.
If your project requires a belt with a strong grip, GT3 is what you are looking for!
