By combining Powr-Grip's W4950A1R Vacuum Cup with a compressed air supply, this product provides a better way to handle glass manually on production lines. The Powr-Grip's W4950A1R Vacuum Cup attaches quickly without any pumping, and it never needs to be re-pumped during operation. The red-line vacuum indicator and continuous vacuum source also make this vacuum cup much safer than the slap-on suction cups sometimes used in such settings.
