Heavy Duty Round Belting
 |
This polyurethane belting is reinforced with a polyester cord for strength. Good for light duty conveying and power-transmission applications, it is chemical and abrasion resistant and creates stronger connections than hollow-core belting. Join the ends with round belt connectors (sold separately) or use a welding kit.
