The AFMPACUSTOM is the heart of every aluminum rack or frame calling for a custom width other than the industry standard 19". AFMPACUSTOM contains 8 aluminum connecting corners, 4 nylon-leveling feet & 96 dog point screws. All eight connecting corners are identical. Since the AFMPACUSTOM is not a complete rack, you'll need a set of width, depth & height rails to build a complete frame.If you don't need a rack with a custom width, a simple alternative is to select from our Pre-Packed Steel Kits with either 10-32 tapped holes or 3/8" square holes, in all available heights and 4 separate depths; 13", 20", 25" or 30" or from our Pre-Packed Aluminum Kits with 10-32 tapped holes in all available heights and 4 separate depths; 13", 20", 25" or 30". All Pre-Packed Rack Kits have the industry standard 19" width.
