The Matte Black Laguna Series Adjustable Bottom Floor Guide is a component for sliding glass door systems, engineered to keep the glass door aligned so it can slide straight while opening and closing. This guide prevents the door glass from being pushed in at the bottom, maintaining the position of the panel. Constructed from stainless steel, the guide is finished in matte black. It is compatible with 3/8" and 1/2" tempered insulated glass doors. The overall length of the guide is 1-15/16" and the height is 7/8". This floor guide is part of the Laguna Series sliding glass door systems, providing a functional solution for maintaining door alignment in architectural and storefront applications. All users are responsible for consulting a structural engineer to determine the suitability of the product for the intended use and site conditions. Installers must be qualified and have professional knowledge about compliance with local, state, and federal regulations, safety factors, and the appropriate choice of fixing material and procedures.
