We are happy to offer one of the best industrial grades of duct tape on the market. The applications listed on the polyken spec sheet greatly underestimate the uses of this product. They say waterproof repairs heavy duty packaging and bundling seaming underlayment materials seaming and sealing for pe traps etc. If those are your uses contact us we can offer less expensive alternatives. If you want a product that will hold up to tremendous wear and tear that can be used for protection in abrasive situations that can withstand the pressures of really nasty stuff being shot at it this is your answer. Besides the industry standard sizes of 48mm 2 inch and 72mm 3 inch we cut lots of narrow widths and offer those as well specifically 1 4 inch and 1 2 inch. See our store on this site for other alternatives. We ve put all our polyken 253 and polyken 231 in open case lots.
