The ProLine G2 Subpanel is part of the new patent pending EZ-Load Mounting System which was designed to maximize space utilization and to make loading the subpanel faster and safer by providing a variety of loading options. The EZ-Load Glide Blocks can be used to load a subpanel vertically from the front, rear or side. Additionally, they can be used to load the subpanel horizontally.a new method for a more controlled option to load a subpanel into a modular enclosure. Features: Accommodates five loading options: vertical front, vertical side, vertical rear, horizontal front (frame over subpanel), horizontal rear (subpanel lowered into frame); High space efficiency ratio (HxW of subpanel)/(HxW of frame) of 84 percent; Mounting subpanel is securely fastened at the top and bottom of the enclosure; subpanels less than 1200mm wide include four sets of EZ-Load Glide Blocks, four BV-M6 fasteners (block to frame) and four M12 Hex Bolts (subpanel to block); Subpanels 1200mm and greater include eight sets of EZ Load Glide Blocks, eight BV-M6 fasteners (block to frame) and eight M12 Hex Bolts (subpanel to block) to ensure wider subpanels are well supported; Subpanels greater than 1000mm wide are 11 gauge (3.0 mm) mild steel, while subpanels 100mm or narrower are 12 gauge (2.5mm); conductive or white painted finish available; Subpanels can be mounted at any depth in 25-mm increments (front to back); accommodates back-to-back and fully recessed rear positions; Side-mount panels must be used for the sides of the enclosure; they can be installed on the interior sides of frames; Optional panel support bracket available for applications requiring more support in the center of the subpanel; this is required if the enclosure will be tipped in transit or if the panel is not located at the bottom of the enclosure on the glide blocks
