Overall (mm): length 396, width 296, height 137
- Festool lists the SYS3 M 137 (204841) at 396 × 296 × 137 mm (15-9/16" L x 11-5/8" W x 5-6/16" H); the number in the name is the height in mm.
- The file is a box envelope of those numbers; Festool's T-LOC latch, lid handle, stacking ridges and side handles are not modelled because their geometry is not published.
- All Systainer3 items share the 296 mm depth so M (396 mm), L (508 mm) and XXL (792 mm) cases couple to each other.
- True size, no printing tolerance added. Only published numbers are used; anything not published is said so.
