A set of four casters (two locking, two non-locking) that mount directly to the bottom of a ProLine frame, 0-mm or 100-mm Solid Base or a Console. (Do not use on plinth bases.) Casters elevate the enclosure 110 mm (4.33) when installed. Caster frames are plated steel with ball-bearing pivots. Caster wheels are made of a black polyamide material. Kit includes M12 mounting hardware. Casters Maximum Load: 1000 lb. (453 kg) NOTE: Casters are designed for moving the cabinet short distances within the building interior space. They are not intended for transportation or shipping. When transporting the cabinet by carrier, the shipping pallet must extend to the frame of the cabinet and at no time should the caster support any load during the shipping process. Casters must have smooth, flat, hard surfaces to move upon. Floors with cracks, seams, debris, inclines, and declines are to be avoided. Great care must always be observed when moving cabinets to avoid tipping. Casters are not designed for exterior surfaces, asphalt, gravel, and other soft surfaces.
