Abstract: A panel support system for mounting a panel to an enclosure can include support profiles mounted to a top and a bottom of the enclosure. The support profiles can define elongate channels that can be sized to receive a top or bottom portion of the panel. The bottom support profile can have apertures along a base wall of the profile. Elements for reducing friction, including, for example, rollers can extend through the apertures in an installation configuration, to facilitate insertion of a panel into the elongate channel. The friction-reducing elements can be moved to an installed configuration once the panel is in place, allowing the panel to rest on the base wall of the bottom support profile.
