Measure the outside frame for H and W. Use decimals, such as 23.375. Changing units converts the number you entered; it does not convert a nominal label into an actual size.

Common Configurations

Choose an example, then edit any dimension. These are nominal inch sizes, subject to configuration review.

Nominal and actual sizes can differ. The reference construction measures 592 × 592 × 381 mm for the 24″ × 24″ × 15″ example. Confirm the actual size before ordering.
