The Notch Portawrap has significant corrosion resistance and tree protection. The rust-proof stainless-steel Portawrap will stand up to the worst heat, salt and humidity that a coastal company can throw at it. The main tube on the Notch Portawrap is seamless, maximizing its strength-to-weight ratio. Seamless tubing is ideal for more stressful applications requiring higher quality, increased mechanical properties, uniformity and strength. Notch has all edges on the main tube and solid posts chamfered to eliminate any sharp edges.
