The Wheels n' Heels® InVent is the newest addition to the Wheels n' Heels® family of grate products. This product type offers the same high strength to weight ratio, excellent appearance and compliance with AASHTO and ADA and High Heel requirements as the Metro type along with being bicycle friendly. The major difference with the InVent style is that the main support bearing bars are hidden under the top surface bars and run in the direction perpendicular to the top surface bars. This feature allows OGi to offer you the most flexibility in product types to fit the grating supports of your project. A slip resistant surface is recommended to meet ADA guidelines. Also available in Stainless Steel upon request.
