Each display is designed to at least 100 standard size die cast collectables that are mounted on a 4.25" card (This is the most common size for die cast that are still in the original package.). Number of cars held will vary depending whether or not cards are overlapped on the display. When over 11 cars are displayed in a column, some of the card may extend above the display board. Made of sturdy 0.25" wood panel, framed on the back by 1" wide sturdy pine wood, has 3 hangers (50-pound capacity) mounted to be hung on 16" center. Rails to hold cars durable plastic. Measures approximately 23" tall and 48" wide. Please note these are not designed for cars with thick plastic covers or cases. The lip of the strip is about 3/8" wide (this is what covers one side of the card) and the thickness is about 3/16", so any card thicker than that would not fit. All joints are glued using water resistant wood glue. Strips are hot glued on using Gorilla Hot Glue. Stronger angle joints are used on corners instead of weaker butt joints.
